Solve Using the Square Root Property 5x^2=20

Problem

5*x2=20

Solution

1. Isolate the x2 term by dividing both sides of the equation by 5

x2=20/5

x2=4

2. Apply the square root property by taking the square root of both sides, remembering to include both the positive and negative roots.

x=±√(,4)

3. Simplify the square root of the constant to find the final values for x

x=±2

Final Answer

x=±2
