    Many may not know but the TI-36X Pro can solve a linear equation like your 2x=10 with its numeric-solver.

What you want to do is solve the linear equation 2x=10 to find the value of the unknown x that makes the equality true. Solving an equation usually involves rearranging therms, factors and so on. However your calculator was not designed to handle the solution of equations, no matter how simple they are.
Some Casio scientific calculators can solve some types of equations (polynomials of degree 2 or 3, simultaneous linear equations in up to 3 unknowns). These are the FX-115 ES (Plus) and FX-991 ES (Plus C). Other equivalent models are sold in the world under different names.

SOURCE: Inputing factors on a casio fx-115es calculator

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

My Casio fxfx-85ES does this, You need to press the S<>D button above the Del button. it is a bit annoying becasue you have to do it every time your turn it of.

SOURCE: Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

SOURCE: Hi there, I have a Casio fx-83GT Plus. At the moment when I do a sum 0.009x0.009 (for example) it gives me an answer of 8.1x10 to the power of -5. How do I get the calculator back to just giving '

Press SHIFT MODE 8 2 to select the Norm2 display mode.
Be aware that the calculator will switch to scientific notation if the magnitude of the number goes above 10^10 or below 10^-9.

SOURCE: how do i change the mode on my Casio fx-82au plus calculator?

Press SHIFT [MODE] to bring up the mode screen. Press 8 for NORM, then 2.
Bear in mind that if the magnitude of the number is too large or too small the calculator will switch to scientific notation anyway. For example, if a number has twenty leading zeros then it won't fit on the display unless it displays it as a power of ten to the negative twenty.

How do i enter a quadratic formula into this model calculator ?


I don't have the specific model of calculator that you referenced, but hope to give you guidance that will work on any calculator.

As an example, let's find the roots of 2x^2 - 10x + 12
In this case a=2 b=-10 and c=12.

(-(-10)+ sqrt ((-10)^2 -(4 * 2 * 12)))/(2*2)

and to find the other root,

(-(-10) - sqrt ((-10)^2 -(4 * 2 * 12)))/(2*2)

All the brackets may be necessary to make sure the calculator does the calculation correctly.

Take care,

Paul

I need to understand how to divide a binomial.


Let's take 2x^2 - 10x +12 and divide it by x-2.
__2x_-_6____________
x-2 ) 2x^2 - 10x + 12
2x^2 - 4x
------------
- 6x + 12
- 6x + 12
------------
0


How many times does x go into 2x^2. Put the answer, 2x above the 2x^2. Next mulitply (x-2) by 2x and put the answer under 2x^2. Now subtract that answer from 2x^2 - 10x and we get -6x (-10x - (-4x)).

How many time does x go into -6x. -6 time. Write this above the line and put the answer above the -10x. Next multiply (x-2) by -6 and put the answer under the -6x. Subtract and we get 0 and we are done. If we want to check our answer we can multiply (x-2) and (2x - 6) and we should get 2x^2 - 10 x + 12.

Good luck.

Calculating chemistry 1 scientific equation divided into another?


Use the rules for exponents and you will calculate it by hand
(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3
To enter powers of 10 use the short-cut key [EE]
For example to enter 6.02*10^23 type in 6.02* [EE] 23. When you use the EE key, the base (10) should not appear.

How do I use this calculator to find the x and y intercepts when the problem has both the x and y letters. it will not allow me to enter the full equation. example problem is 2x-5y=20 and I need to find...


x-intercept (or zero of the function)
Set y=0 in the equation and solve fo x: 2x-5(0)=20 and x=20/2=10

y-intercept (initial value)
Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4

If the equation is in the slope-intercept form y=ax+b
1. y-intercept is b
2. To get the x-intercept ( zero of the function) Set y=0=ax+b, and x=-b/a

For instance if I have a problem of 4x+1-x=2x-13+5. how do I enter it in my T E to find wha is X


Hi,
This calculator does not have a Solve function or a solver. However this example of yours is very simple that you can do it by hand. If you do not mind I will show you how to solve it. Not everything needs a calculator.
You want to solve for x. OK
  1. Start by gathering similar terms 4x-x =3x; -13+5 =-8
  2. Rewrite your equation as 3x+1=2x-8
  3. Make the +1 change side while changing its sign
  4. 4x+1 -1 = 2x-8 -1 or 4x=2x-9
  5. Make +2x on the Right hand side go to the left hand side, changing its sign in the process 4x-2x=-9 or 2x=-9
  6. Divide both members by 2. This gives
  7. x=-9/2 or -4.5 if a decimal result is required.
Hope it helps.

Chemistry problem


You enter a pH value and change the sign to minus, then hit 2nd LOG which is 10^x. The x value is what you're looking for. To put the answer in scientific notation, press 2nd 5 to do so.

Example:

For a pH = 4.1

-4.1 2nd LOG will return 0.0000794

Hiting 2nd 5 will express it as 7.94 -5, giving you the [H+] concentration.

Memory and memory recal


The STO> button just above the on/off button is your memory store initializer.
example: 2x + 53 STO> y
stores "2x + 53" in a variable named "y".
To recall, just hit y and enter. In fact, if you type an equation like 3y^2 - 4y it will insert the data in for every "y" and give you:
(2x + 53)(6x + 155) as an answer.
To clear the memory:
DelVar y or F6 (2nd+F1) and clear all w/ single character names.
To recall a prevous answer, 2nd+(-) or type ans(1) for the last answer. You can also type ans(2) for the 2nd to last answer & so on.
