Use the quadratic formula

Theory

Use the quadratic formula

The quadratic formula can be used to solve quadratic equations, ax2+bx+c=0.ax^2+bx+c=0. x=-b±b24ac2a x=\dfrac{\text{-} {\color{#009600}{b}} \pm\sqrt{{\color{#009600}{b}}^2-4{\color{#0000FF}{a}}{\color{#FF0000}{c}}}}{2{\color{#0000FF}{a}}} Here, aa is the coefficient of the x2x^2-term, bb is the coefficient of the xx-term, and cc is the constant.
