It is a method to Solve Quadratic Equations .
Please remember that in actual practice unless you're told that you use completing the square method, you will probably not use this method.
Suppose you need to solve the following Quadratic equation by completing the square method (I have selected a problem where coefficient of
First step is to keep all terms containing
Now take half of the coefficient of the
square it, and add that value to both sides of the new equation.
In the example we have coefficient of the
On inspection we see that we have made LHS a perfect square which can be written as
Take square root of both sides and remember to use both
The two roots of the given equation are
