What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

How do I enter ln55-1 divided by 2? The answer is 1.5 however I'm coming up with 1.99


Be careful with the order of operations. Try (ln(55)-1)/2You can never have to many parenthesis. remberr PEMDAS ln is an exponent so you want to put it inside parenthesis in oder to follow the Order of operations.

How to convert Fahrenheit to Celsius


Put 70 in for F, and apply BEDMAS, the order of operations, brackets, exponents, division and multiplication, and finally addition and subtraction. In this case, we have to do the brackets first before the multiplication and division. The answer should be 21 degrees Celsius.

What is the answer to to this (x^5)^3(x^3)^4


We have to follow BEDMAS, the order of operations, where brackets are first, then exponents, followed by division and multiplication, and finally addition and subtraction.

Also, we have to use the exponent law of an exponent to an exponent, we multiply the exponents with the same base.

If we forget this, we can always do it the long way.

(x^5)^3 = (x^5)(x^5)(x^5) = x^15

Similarly, (x^3)^4= (x^3)(x^3)(x^3)(x^3) = x ^12

Now that we have done the exponents, we can multiply x^15 by x^12 and get x^27.

Good luck.

I have a TI-84. It gives me a syntax error when I try to enter problems with negative exponents.


Use the (-) key (just to the right of the decimal point key) instead of the - key when entering a negative number (not just exponents).
- is used to subtract one value from another. (-) is used to negate a value. - operates on two numbers, (-) operates on one.

I need to know how to enter anything above cube root into my TI-83.


  1. Use the universal power key marked with [^].
  2. To avoid problems if the exponent is an expression, enclose it in parentheses.
  3. To enter any power type number^(exponent)
  4. If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
  5. To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
  6. Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

Is it possible to calculate cube root or higher with BA ii plus?


To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.
it gives the cube the 4th power, 5th, 6th, etc.
If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.
When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

Negative exponents? .825/(10^(-3)) ? Not sure how to get it to do the negative exponent.


You entered it correctly. Although you can leave out the parentheses if you want. The calculator will do exponents before it does multiplication or division just like it does multiplication and division before it does addition and subtraction. It has a built in order for hierarchy of operations. You only need to use parentheses if you want to do something that is different from this order. FYI, dividing by a negative exponent is the same as multiplying by a positive exponent. You could enter it in either way. .825/10^-3 = .825*10^3 = 825. I hope this helps you out.
