In solving equations we must always do the same thing to both sides of the equation. An alternative method to solve a quadratic equation is to complete the square. Put the x -squared and the x terms on one side and the constant on the other side.
Divide both sides by the coefficient of x -squared unless of course its 1.
Completing the square is a method used to determine roots of a given quadratic equation. A quadratic equation can also be solved by factoring using the square roots or quadratic formula. To solve a x 2 b x c 0 by completing the square. Completing the Square - Solving Quadratic Equations.
