Deriving the Quadratic Formula (Proof Video)

In this video, I will show you the proof or derivation of the quadratic formula. The quadratic equation is ax^2 + bx + c = 0, where a != 0. If you want to solve for x, the formula is x = (-b +- sqrt(b^2 - 4ac))/2a. In this video, I will show you how to prove the quadratic formula or show you how to derive the quadratic formula. You will need to complete the square. This is a useful topic that math students need to know.
