The quadratic formula helps us solve any quadratic equation. The proof is done using the standard form of a quadratic equation and solving the standard form by completing the square. An alternative way of deriving the quadratic formula is via the method of Lagrange resolvents which is an early part of Galois theory. It shows a man solving this problem using a black board and chalk to clearly demonstrate the method of plugging in the respective coordinates to arrive at an answer.
