## Summary

The quadratic formula is a useful tool for solving quadratic equations. It can be derived by completing the square of a quadratic equation 1 , and is one of the most important formulas in mathematics. The formula is written as ax² + bx + c = 0, where a, b, and c are constants, and x is the unknown variable. The solution to the equation is given by x = /2a. This formula can be used to solve a variety of equations, from simple to complex.
