Any equation in the form ax%5E2%2Bbx%2Bc graphs to a parabola. A lot of times those equations can also be factored. Your equation cannot be factored as there are no two numbers when multiplied together is 1 and when added together is -4. So, to solve it, you'll need to use x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29. The graph looks like:
