Question

Factor by grouping (write out all of the factoring)
3x^2+18x-6x-36

Answer 1

3(x + 6)(x - 2)

Explanation:

Given

3x² + 18x - 6x - 36 ← factor out 3 from each term

= 3(x² + 6x - 2x - 12) ( factor the first/second and third/fourth terms )

= 3(x(x + 6) - 2(x + 6)) ← factor out (x + 6) from each term

= 3(x + 6)(x - 2)
