Factoring Polynomials

To factor by grouping, we will take the greatest common factor of the first three terms and the greatest common factor of the last three terms.

3 a x + 2 a y - a z + 3 b x + 2 b y - b z

a

a (3 x + 2 y - z) + 3 b x + 2 b y - b z

FactorOutFactor out

b

a (3 x + 2 y - z) + b (3 x + 2 y - z)

FactorOutFactor out

(3 x + 2 y - z)

(a + b) (3 x + 2 y - z)
