factoring polynomials
I need help with a challenge problem I'm attempting to solve in my math book.
The first one is: Factor $4x^2(x-3)^3-6x(x-3)^2+4(x-3)$
I worked through the problem and got {$[x-3][4x^2(x-3)^2-6x(x-3)+4]$}.
Could someone please look at this and tell me if I'm correct, wrong, or
even close to the right answer.
