Hello! A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b, and c are real numbers and a ≠ 0. It is called a quadratic equation because it involves the square of an unknown variable (x). The solutions to a quadratic equation can be found using the Quadratic Formula: x = -b ± √b2 - 4ac/2a. This formula can be used to solve any quadratic equation, no matter how complex. In addition, there are several methods for solving quadratic equations without using the Quadratic Formula. These include factoring, completing the square, and graphing. I hope this helps!
