Question

Find ALL the zeros for the function: f(x)= 10x^3-15x^2-16x+12. So far I have worked it down to 5x^2(2x-3) + (-4(4x-3)). Im stuck because usually my numbers in the parentheses match. Where do I go from here?

Answer 1

It could be that you wrote down a wrong number. If not then this can not be factor by group.

Answer 2

I wrote down the correct numbers. how do i complete it from here if I can't factor by group?
