There is also a general solution (useful when the above method fails), which uses the quadratic formula: Use that formula to get the two answers x + and x − (one is for the "+" case, and the other is for the "−" case in the "?

A quadratic equation is an equation that can be written as ax ² + bx + c where a ≠ 0. In other words, a quadratic equation must have a squared term as its highest power. Below are the 4 methods to solve quadratic equations. Click on any link to learn m

Every quadratic equation has two values of the unknown variable usually known as the roots of the equation (α, β). The roots of a quadratic equation can be obtained by factoring the equation. For this reason, factorization is a fundamental step towards
