Completing the Square Steps
Lets assume the quadratic equation is as ax2 + bx + c = 0. Follow the steps to solve it using the completing the square approach.
Step 1: Form the equation in such a way that c is on the right side.
Step 2 : Divide the entire equation by an if an is not equal to 1, such that the coefficient of x2 equals 1.
Step 3 : On both sides, add the square of half of the term-x coefficient, (b/2a)2.
Step 4 : Factor the left side of the equation as the binomial term’s square.
Step 5: On both sides, take the square root.
Step 6 : Find the roots by solving for variable x.
Following these steps one can easily solve quadratic equation by completing sqaure method.
Note: Sometime while using completing the square method one might encounter (-1) inside the roots and in that case the roots of the quadratic equation are complex.
