    1. The problem statement, all variables and given/known data

    The answer to one of my maths questions is;

    $$\frac{60x^{4}-240x}{3x^{4}+x^{3}-14x^{2}+4x+8} $$

    2. Relevant equations



    3. The attempt at a solution

    Can this be simplified to;

    $$\frac{20x^{4}-60x}{x^{3}-14x^{2}+8} $$

    The first fraction you show seems to be in the simplest form. It can't be simplified to the 2nd fraction. If you want to know where you went wrong, you might try showing the steps you took to get there.

    One indication that they are not related is the first fraction has equal degrees (4), while the second does not (4, 3).

    Thanks, I forgot about comparing the degree of the polynominals to check my answer.

    I know the steps before it are right, I was just checking I'd got the answer into its simplest form.
