Well, what is the quadratic formula for a general quadratic: $$ax^2 + bx + c = 0$$?

2. AccessDenied

Once we have that established, we simply have to plug in the corresponding a, b, and c into the formula and evaluate.

3. AccessDenied

The quadratic formula is: $$\displaystyle x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ From here, it is simply taking the a, b, and c from the original equation and inserting them. Please respond if you are having any issues. :)
