You need to divide each term by -6x^2. So the expression becomes 12x^5/-6x^2 + 24x^4/-6x^2 - 12x^2/-6x^2 = -2x^3 - 4x^2 + 2x.

Katherine, Subtraction is just adding the opposite. For example, if I have 5 - 7, I could rewrite it as 5 + -7. This is simple algebra. For your problem, it can be rewritten as 3x2 + -5y + 2xy + -x + -7.
