**Quidditch**, Sunday, September 5, 2010 at 11:34pm1. Make sure the equation is in the form:

ax^2 + bx + c = 0, which your problem is.

2. Use the quadratic formula:

x1 = (-b + (b^2 - 4ac)^(1/2))/(2a)

x2 = (-b - (b^2 - 4ac)^(1/2))/(2a)

You can check your answers by substituting into the original equation.
