# Factoring Worksheet

This factoring strategy was taken from the Integrated
Review on page 380 in your text.

It gives a general strategy for factoring polynomials . Read through it and then
try to use

the general method to factor the following polynomials.

** Factoring a Polynomial
**

1. Are there any common factors ? If so, factor out the GCF .

2. How many terms are in the polynomial ?

(a) If there are

**two**terms, decide if one of the following can be applied.

i. Difference of two squares :

ii. Difference of two cubes :

iii. Sum of two cubes :

(b) If there are

**three**terms, try one of the following.

i. Perfect square trinomial :

ii. If not a perfect square trinomial , factor using the methods presented in 6.2

and 6.3.

(c) If there are

**four**or more terms, try factoring by grouping.

3. See if any factors in the factored polynomial can be factored further.

4. Check by multiplying .

And a few more difficult ones.
