What is Completing the Square?

Completing the square is a math technique used primarily in algebra to solve quadratic equations. It involves manipulating an equation to transform it into a perfect square trinomial, which can then be easily solved using other methods.

Why is Completing the Square Important?

While completing the square may seem like a specific skill that's only useful in certain situations, it actually has a number of practical applications. For example:

It can be used to find the maximum or minimum value of a quadratic function.
It can be used to solve optimization problems, such as finding the dimensions of a box with a given volume and minimum surface area.
It is a fundamental building block for more advanced topics in math, such as calculus and linear algebra.

How to Complete the Square: Step-by-Step

Here is a basic overview of how to complete the square for a quadratic equation in standard form (ax² + bx + c = 0):

Ensure that the coefficient of the x² term is 1. If it is not, divide the entire equation by that coefficient.
Move the constant term (c) to the right side of the equation.
Divide the coefficient of the x term (b) by 2, and then square the result. This gives you the number you need to add and subtract to the left side of the equation in order to create a perfect square trinomial.
Add and subtract the number from step 3 to the left side of the equation, and then factor the resulting trinomial.
Solve for x using the quadratic formula or other methods.

Examples of Completing the Square

To better understand how completing the square works, here are a few examples:

Example 1:

x² + 6x + 5 = 0

Step 1: Divide by the coefficient of x².

x² + 6x/1 + 5/1 = 0

Step 2: Move the constant term to the right side.

x² + 6x/1 = -5/1

Step 3: Divide b by 2 and square the result.

b/2 = 6/2 = 3

(3)² = 9

Step 4: Add and subtract the number from step 3.

x² + 6x/1 + 9 - 9 + 5/1 = 0

(x + 3)² - 4 = 0

Step 5: Solve for x.

x + 3 = ±2

x = -3 ± 2

x = -5, -1

Example 2:

2x² - 4x - 6 = 0

Step 1: Divide by the coefficient of x².

x² - 2x - 3 = 0

Step 2: Move the constant term to the right side.

x² - 2x = 3

Step 3: Divide b by 2 and square the result.

b/2 = -1

(-1)² = 1

Step 4: Add and subtract the number from step 3.

x² - 2x + 1 - 1 = 3

(x - 1)² = 4

Step 5: Solve for x.

x - 1 = ±2

x = -1 ± 2

x = -3, 1
