Quadratic Equation

A polynomial equation of the second degree, generally taking the form $ax^2 + bx + c = 0$, where $x$ represents an unknown variable, and $a$, $b$, and $c$ are constants with $a \neq 0$.

Example

The equation $2x^2 - 5x + 3 = 0$ is a quadratic equation. It can be solved using the quadratic formula $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ to find its roots.
