    It's a formula used to solve equations of the form ax^2 + bx + c = 0 where a, b, and c are known coefficients and x is the unknown variable.  Here is a link with the formula and derivation:


    You can program the formula into a graphing calculator or use an online quadratic equation solver.  If the graph of the parabola  y = ax^2 + bx + c does not intersect the x-axis, the two roots will be complex, otherwise they will be real.
