Introduction

The square-root property is a fundamental concept in algebra that allows us to solve equations involving square roots. In this article, we will focus on solving equations using the square-root property, specifically the equation 2(x6)2=82(x-6)^2 = 8. We will break down the solution step by step and provide a clear explanation of each step.

Understanding the Square-Root Property

The square-root property states that if x2=ax^2 = a, then x=±ax = \pm \sqrt{a}. This means that if we have an equation involving a square root, we can eliminate the square root by taking the square of both sides of the equation.

Step 1: Divide Both Sides by 2

To solve the equation 2(x6)2=82(x-6)^2 = 8, we first need to isolate the squared term. We can do this by dividing both sides of the equation by 2.

2(x6)22=82\frac{2(x-6)^2}{2} = \frac{8}{2}

This simplifies to:

(x6)2=4(x-6)^2 = 4

Step 2: Take the Square Root of Both Sides

Now that we have isolated the squared term, we can take the square root of both sides of the equation. Remember that when we take the square root of both sides, we must consider both the positive and negative square roots.

(x6)2=4\sqrt{(x-6)^2} = \sqrt{4}

This simplifies to:

x6=±2x-6 = \pm 2

Step 3: Solve for x

Now that we have the equation x6=±2x-6 = \pm 2, we can solve for x by adding 6 to both sides of the equation.

x=6±2x = 6 \pm 2

This gives us two possible solutions:

x=6+2=8x = 6 + 2 = 8

x=62=4x = 6 - 2 = 4

Conclusion

In this article, we solved the equation 2(x6)2=82(x-6)^2 = 8 using the square-root property. We broke down the solution into three steps: dividing both sides by 2, taking the square root of both sides, and solving for x. We found two possible solutions: x=8x = 8 and x=4x = 4.
