About Quadratic Equations

Learn how the quadratic formula computes real and complex roots for any second-order polynomial.

Instant Solutions

A quadratic equation is a second-order polynomial equation in a single variable $x$, written in standard form as $ax^2 + bx + c = 0$, where $a \neq 0$. The roots of the equation can be accurately determined using the quadratic formula:

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