## Solving Quadratic Equations by Completing the Square

Step 1: When the coefficient of the quadratic term ( a) is different from 1, we divide the quadratic equation by a so that we obtain an equation with a value of a equal to 1: x 2 + b x + c = 0. Step ## How to Solve a Quadratic Equation by Completing the Square

The completing the square formula is given by, ax2 + bx + c ⇒ a (x + m)2 + n Where, m = b/2a, n = c – (b 2 /4a) Here, m can be any real number and n is a constant.
