Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

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.

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.

Testimonial: "Thanks so much, its working now:) I thought I was going to have to buy a new calculator!"

1. Press (AC)
2. Hold (Rate) for about 2-3 second
3. Press (Set / TAX+)
4. Input the tax rate
5. Press (Set / TAX+)
6. Hold (Rate) for about 2-3 second again
7. Press (Set / TAX+) again
And Then you can test the rate .

If you want to get really basic and not mess around with a lot of fancy buttons and whatnot, simply put in 3.2 X 10 then push the ^ button and then (-)7. Over to the left, the third button down should look like ( - ), push that and then the 7 to avoid all the parethesis mistakes.

### Hi,how can I calculate median using fx-570es plus?

The median is the number is the middle.

Using the calculator, you can follow the Statistical Calculations (Stat) on pages 22 and 23 of the attached manual. http://support.casio.com/pdf/004/fx-570_991ES_PLUS_E.pdf

However, it might be quicker to just put the numbers is order from lowest to highest and pick out the number in the middle.

For example, take the numbers 3, 5, 4, 7, 6, 4, 9.

Putting them in order, we get 3, 4, 4, 5, 6, 7, 9

There are 7 numbers so we want the 4th number (3 numbers to the right and 3 numbers to the left). In this case, the 4th number is 5 and that is our median, as half the numbers are lower than it and half the numbers are higher than it. It the number of numbers is even, you take the average of the two middle numbers.

Good luck,

Paul

### The words FIX DEG appear on the screen and I can't get rid of it. It doesn't calculate properly

DEG says that the angle unit is set to degrees. You can change it to RADians, or GRADs. However much you want to get rid of all of them you will always have one of them. Learn to live with them.
FIX says that the decimal displays will always show a fixed number of decimals. You can decide how many you keep. Apparently your calculator is configured not to show any decimal digits: the number of fixed digits is set to zero. Change it to some other number
There are other display formats : Engineering ENG, and Scientific (SCI)
There is another format (possibly 2) called Norm 1 or Norm 2.
Set you calculator to one of the Normal formats.
Press SHIFT MODE to enter (Setup) and configure.
Advice: Learn to use your calculator. The best way to achieve mastery is to look inside the manual whenever you do not understand something.

### How do I calculate the mod function in my casio fx 100ms model

It seemed there is no Modulo function in fx-100MS. But Mod is just the remainder of a division operator.

So if you have A mod B = C, divide A by B, subract the remaining whole number, and multiply it by B to get C.

Example:

7 mod 4 = 3

In the Calculator:

7 / 4 = 1.75, then 1.75 - 1 = 0.75. Then 0.75 x 4 = 3

### When i type in 0.04x0.007 the answer doesnt come in full the zeroz before the decimal dont show up how do i make them show and get the full answer?????

Unfortunately you can't. If the magnitude of the number is too small or too large, the calculator automatically switches to scientific notation. Consider a number that has 30 zeros before it instead of the 3 in this example. How is that going to fit on the screen?

### I can't get the calculator out of the exponent mode. ex. It gives me 7 -03 rather than .007.

Hi,
You must change the number display to FIX. Press [MODE][7:] followed by a number betwee 0 and 7. This will set the number of decimal digits. Be warned that the Indicator FIX will be displayed on the screen.
This information is for the FX250D, but I trust it is also valid for the FX-250HC. If it is not, just look in your manual. If you cannot find yours, do not blame me, I cannot get hold of a manual for this calculator.

You can always take the time to play with the [MODE] key followed by [.] or a number. When you press the mode + number, look on the screen to see what indicator appears (deg, Fix, Rad) The one that makes FIX appaear is the one that gets you out of the exponential scientific mode.

Good luck

### I need to find the antilog to -6.80 on a casioi fx-300ms calculat

Alot of people have this doubt, so I might as well make it clear.

Press the 10^x button (while pressing SHIFT, of course; it's exactly above the LOG button) followed by the number whose antilog you desire.

Example :
Let's say we need antilog(-6.8),
1. Press SHIFT, followed by LOG (i.e 10^x); this'll display a 10 on the screen;
2. Type in -6.8;
3. Press "=";
4. This'll display 1.584893192x10^-7 as the solution, which is correct!
5. Bye, lol :P

Press 1 to choose Fixed format followed by 2 for TWO Digits
3 decimal digits [MODE] ---------[1 ] (Fix) 3
Hope it helps.
