How do you solve this?

(3x+2)(3x^2+5x-4)

2 answers

(3x + 2)(3x^2 + 5x - 4)
multiply:
9x^3 + 15x^2 - 12x + 6x^2 + 10x - 8,
Combine like-terms:
9x^3 + 21x^2 - 2x - 8,
Group the 4 terms into factorable pairs:

(9x^3 + 21x^2) + (-2x - 8),
3x^2(3x + 7) -2(x + 4),
This cannot be completely factored.
NOPE!!!!!!!!!!!!!!!!!!!! I can't solve it. Sorry. :-(
