Lesson 9: Factoring by Grouping
Polynomials with four terms can be factored by removing the greatest common factor from a pair of terms followed by a binomial common factor.
Steps:1) Group into pairs of terms (first two and last two).2) Find common factor of each group separately.3) Find common factor between each group.
Examples: Factor.
1) x2+3 x+6 x+18
2) 6a2−8 ab+3ab−4 b2
3) pq+ pr−sq−sr
4) 2 x2−3 xz−2 xy+3 yz
5) a2 x+a2 y−36 x−36 y
