Factoring by Grouping

Factor Quadratic Polynomials:

WHAT TO DO:	HOW TO DO IT:
Look at the polynomial's 4 terms to see if they can be grouped two terms by two terms. Bring down the middle sign.	x² + 7x + 2x + 14 x² + 7x + 2x + 14
Find the common factor for each group. The factors in parentheses are the same for both groups.	x(x + 7) + 2(x +7)
Now, the common factor in each group is (x + 7). Underline it.	x(x + 7) + 2(x + 7)
Factor out the common factor	(x + 7)(x +2) Answer
⇒ Check by multiplying back out by FOIL method. First - Outer - Inner - Last Note O-I terms.
Try another:	3x² - 9x + 2x - 6
Group 2 Ã— 2:	3x² − 9x + 2x − 6
Factor common factors	3x(x − 3) + 2(x - 3)
Factor common terms in ( ... )	(x − 3)(3x + 2) Answer
Check by multiplying FOIL:
