» Solveur d’équation du second degré

Solve quadratic equations quickly with step-ready results for both roots.

$$ax^{2}+bx+c=0$$

$$x^{2}+4x-12=0$$

$$x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$$

$$x=\frac{-4\pm\sqrt{4^{2}-4\cdot1\cdot(-12)}}{2\cdot1}$$

$$\begin{aligned} x_1&=2\\ x_2&=-6 \end{aligned}$$
