What are the steps to solving a quadratic equation by completing the square?
Completing The Square Steps Isolate the number or variable c to the right side of the equation. Divide all terms by a (the coefficient of x2, unless x2 has no coefficient). Divide coefficient b by two and then square it. Add this value to both sides of the equation.
What is the process of completing the square?
Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial . To solve ax2+bx+c=0 by completing the square: Add the square of half the coefficient of the x -term, (b2a)2 to both sides of the equation.
