# Solving Quadratic Equations by Completing the Square

I Move the Constant Term to the RIGHT side of the equation,
Move the x2 and x terms to the LEFT side of the equation.

II Get a leading coefficient of 1 (i.e. 1x2 + ...). If necessary, divide both
sides of the equation by the coefficient of x2 .

III Complete the Square by

Taking 1/2 of the coefficient of x ,
Square this result ,
Then add the squared result to Both Sides of the equation.

IV Factor the Perfect Square Trinomial on the left side of the equation.

V Use the Square Root Method (take the Square Root of Both SIDES of the
equation ) to solve the resulting equation.
