I assume you're solving for "x"?

Are you familiar with long division and/or synthetic division?

Personally, I would at first try to avoid division and try to factor. There is a neat trick for factoring things like 3x^2 - 11x - 4. Normally this is a bit tricky, because of the 3 in front of x^2. The trick is this: 1. remove the 3 and multiply it with the last term: x^2 - 11x - 12 (something different!) 2. factor this one: (x + 1)(x - 12). 3. divide 1 and -12 by 3: (x + 1/3)(x - 4) 4. if there are fractions, remove these by multiplying again: (3x + 1)(x - 4). Now you have the right factorisation of 3x^2 - 11x - 4. This means that dividing it by x - 4 gives 3x + 1. Otherwise, you could do the long or synthetic division.
