    use the formula ax^2+bx+c \[x=(-b \pm \sqrt{b ^{2}-4ac})/2a\]

    For example, for the quadratic equation x2 + x - 12 = 0, x = 3 and x = -4 are both roots ... 9x2 = 81 (a = 9, b = 0, c = -81 since we could subtract 81 from both sides) ...

    Quadratic Equations AlgebraIn this case, the equation x2 - x - 2 = 0 can be broken apart into two factors [i.e., ... 9x2 = 81 (a = 9, b = 0, c = -81 since we could subtract 81 from both sides) ...
