(5x^3 - x^2 - 60x + 12)/(5x-1)
First, I’m going to factor the top. I’m going to factor by grouping.
The GCF of 5x^3 - x^2 is x^2. I pull x^2 out and am left with x^2(5x-1)
The GCF of 60x-12 is 12. I pull out 12 and am left with -12(5x-1). The fully factored expression looks like this:
(x^2-12)(5x-1)
I am now left with (x^2-12)(5x-1)/5x-1.
The 5x-1s cancel out. I am left with x^2 - 12
