Question

Factor the GCF: 9a4b3 + 24a3b2 − 15a2b.

3a2b(3a2b2 + 8ab − 5)
3a2b3(3a2 + 8ab − 5)
3a2b(3a2b + 8ab − 5b)
3ab(3a3b2 + 8ab − 5a)

Answer 1

I know its either A or C, im just confused on whats in the parenthesis

Answer 2

ok hold on, ill try and do it

Answer 3

The greatest common factor is defiantly 3a^2b

Answer 4

yes, now just pull that out from each term, what is left

Answer 5

yea thats the part that really confuses me i dont know how to do that

Answer 6

divide each term by that 3a^2b

Answer 7

ok give me a minute

Answer 8

3a^2b^2, 8ab^2, 5

Answer 9

yes, except the coefficient for the last is -5, so put it together

Answer 10

3a^2b (3a^2b^2+ 8ab^2, -5)

Answer 11

oh, and the middle, you are reducing the b term by a power of 1, so it is

8ab
