Students must master quadratic equations in algebra. Many fields of mathematics and science use quadratic equations to comprehend curves, motions, and calculus optimization. Completing the square turns a quadratic equation into a perfect square trinomial. Completing the square worksheet PDFs can help you perfect this method. This blog will explain how to complete the square, why it’s important, and how a worksheet PDF can help.

What is Square Completion?

Quadratic equations are solved by completing the square. Transforming a quadratic problem into a perfect square trinomial simplifies its solution. Quadratic equations usually look like:

In the equation, ax2 + bx + c = 0.

Where:

A is the coefficient of x^2 and x^x, b is the coefficient of x and c is the constant.
Completing the square simplifies solving for x by expressing the equation as a binomial square.

Why Finishing the Square Matters

Completing the square is crucial because of its benefits:

Completing the square converts quadratic equations into vertex form, making parabolas easier to graph.
Completing the square yields the quadratic formula, a popular approach for solving quadratic equations. Students can learn about the quadratic formula from this procedure.
Completing the square may be easier than factoring or using the quadratic formula to solve quadratic equations.
Quadratic equations are used in projectile motion, economic modeling, and physics. Completing the square makes solving these issues more flexible.

Complete the Square Step-by-Step

Let’s use an equation to explain square completion.

For example, solve x = 2 + 6 x + 5 = 0. complete the square.

Place the constant term on the other side of the equation.

First, rearrange the equation to place the constant term c on the right side.

x 2 + 6 x = − 5 x 2 +6x=−5
The coefficient of x2 should be set to 1 in step 2.

As the coefficient of x2 is already 1, we can proceed to the next step. To convert a non-1 coefficient to 1, divide the equation by a, the coefficient of x2 (x2).

Step 3: Find the square-completing number

Complete the square by squaring half of the coefficient of x (in this case 6).

( 6 2 ) 2 = 9
( 2 6​) 2 =9
Put this integer on both sides of the equation:

x 2 + 6 x + 9 = − 5 + 9 x 2 +6x+9=−5+9
It boils down:

( x + 3 ) 2 = 4
(x+3)
2 =4
In Step 4, solve for x.

With a perfect square trinomial, solve for x by taking the square root of both sides:

x + 3 = ± 2 x+3=±2
Finally, remove 3 from both sides to find x.

x = − 3 ± 2 x=−3±2
For example, x = -1 or x = -5.
