Quadratic equation

A quadratic equation is a polynomial equation of the second degree. The standard form of a quadratic equation is:

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

where $a$, $b$, and $c$ are real numbers, and $a \neq 0$.

To solve for $x$, you can use the quadratic formula:

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

This formula provides the values of $x$ that satisfy the equation. The term $b^2 - 4ac$ is called the discriminant, which determines the nature of the roots (solutions).
