The quadratic formula is the solution to the general quadratic equation,

and it looks like this:

where a, b, and c are the coefficients on the three terms in the equation.

In your problem, , , , and . Now all we have to do is plug in the values of a, b, and c, then do the arithmetic.

So our two solutions, and there are ALWAYS two solutions to a quadratic, are:

and

Hope that helps.
