Completing the Square. In this section, we will devise a method for rewriting any quadratic equation of the form \[a x^{2}+b x+c=0\] in the form \[(x-p)^{2}=q\] This process is called completing the square. As we have seen, quadratic equations in this form can easily be solved by extracting roots. We begin by examining perfect square trinomials:

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 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 this way:

Say you have the equation 3x^2-6x+8=23. To complete the square, first, you want to get the constant (c) on one side of the equation, and the variable (s) on the other side. To do this, you will subtract 8 from both sides to get 3x^2-6x=15. Next, you want to get rid of the coefficient before x^2 (a) because it won´t always be a perfect square.

We can use a method called completing the square. Let's start with the solution and then review it more closely. ( 1) x 2 + 6 x = − 2 ( 2) x 2 + 6 x + 9 = 7 Add 9, completing the square. ( 3) ( x + 3) 2 = 7 Factor the expression on the left. ( 4) ( x + 3) 2 = ± 7 Take the square root. ( 5) x + 3 = ± 7 ( 6) x = ± 7 − 3 Subtract 3.
