Steps for GCF. 1.) Factor out the GCF (divide by 3 for each term) 3x2 ÷ 3 = x2 -6x ÷ 3 = -2x 15 ÷ 3 = 52.) You bring the 3 outside the and put inside the parentheses all the terms you just took the GCF out of. So 3(x2 - 2x + 5)3.) Since you cannot factor out anything else, that would be your final answer. Check your answer by multiplication.

Steps for difference of squares. 1) x 2 - 9STEP 1- TAKE THE SQUARE ROOT OF a AND c = (x 3)(x 3)

STEP 2- IT DOESNT MATTER WHICH SET OF PARENTHESIS IT GOES IN BUT, MAKE SURE YOU HAVE A AN ADDITION AND SUBTRACTION = (x + 3)(x - 3) 2) 4x2 - 16STEP 1- (2x 4)(2x 4) STEP 2- (2X + 4)(2X - 4)

Steps fo perfect square trinmoial. An equation to keep in mind when factoring perfect square trinomials is a 2 + 2ab + b 2 the first term is a 2 and the base is a the third term b 2 and the base is b
 * you can find the base of the terms by taking the square root of the first and the third term.

Now you put the bases in parentheses with a plus sign in between them since the middle term is positive. (a + b) Then put it to the second power and your done. (a + b) 2

Steps for trinomial when A=1

**__Step 1__:** Make two sets of parenthesis and put as follows (x )(x ), because the first step of **FOIL**ing is "**F**irst" and you know that 1x times 1x is the only way to get x 2.

__**Step 2:**__ Find the signs(+ or -) and numbers. To find the numbers, ask yourself "What two numbers have a product of C but a sum of B?".

__**Step 3:**__ FOIL out the factors and check your answer. It should be the same trinomial that you started with.
