3x^2(x-1) - 2x(x+3) - x^2(x+2)
=>3x^3 - 3x^2 - 2x^2 - 6x - x^3 - 2x^2
=>2x^3 - 7x^2 - 6x
=>x(2x^2 - 7x - 6)

multiply 3x^2 by x and by -1. Write down each product.
Do the same for the other terms
Now combine terms with like powers (x^3, x^2, x and constants).

3x^3-3x^2-2x^2-6x-x^3-2x^2
= 2x^3-7x^2-6x
