Given a general quadratic equation of the form. F x a x b 2a 2 - b 2 4a c. That formula looks like magic but you can follow the steps to see how it comes about.
Quadratic equations are also needed when studying lenses and curved mirrors.
See examples of using the formula to solve a variety of equations. Given a general quadratic equation of the form. The quadratic formula helps us solve any quadratic equation. This is the standard form of a quadratic function with h - b 2a k c - b 2 4a.
