Solving quadratic equation:

Step 1: Divide all terms by a (the coefficient of x2).

Step 2: Move the number term (c/a) to the right side of the equation.

Step 3 Complete the square on the left side of the equation by adding square of the half of the coefficient of x [½(b/a)]² and balance this by adding the same value to the right side of the equation.

We now have something that looks like (x + p)2 = q, which can be solved rather easily:

Step 4 Take the square root on both sides of the equation.

Step 5 Subtract the number that remains on the left side of the equation to find x.
