Steps for Factoring Polynomials
Subject:
Algebra [1]
Tags:
1. Pull out greatest common factor or GCF [This is a very important step that is often skipped] Ex: or
2. Look at number of terms
a. 2 Terms: If there are two terms (binomial), then check to see if it is
i. A difference of squares:
Ex:
ii. A difference of cubes
Ex:
iii. A sum of cubes
Ex:
If there are two terms and the expression is none of the above, it is prime!
b. 3 Terms: If there are three terms (trinomial), then factor into two binomials thinking of the FOIL method in reverse.
Find factors of c that add up to b.
Start by identifying the factors of c. The sign before c determines whether signs are the same or different in the 2 binomials that are produced, .
