15 a^2 b c^2 - 9 a^2 b^4 c
= 3 a^2 b c ( 5 c - 3 b^3)
Factor (15a squared bc squared -9a squared b to the fourth c) by finding the gcf.
I think the answer is 3abc(5ac-3ab3). I got it because I found the gcf of the coefficents which are 3. I subtracted one from each exponent so, i canceled b from 15a squared bc squared and c from-9a squared b to the fourth c. Am I right?

No. or Almost. YOu have another a you can pull out as a common factor
3a^2*bc is the gcf.
3a^2*bc is the gcf.
