Solve Using the Square Root Property 3x^2=21

Problem

3*x2=21

Solution

1. Isolate the squared term by dividing both sides of the equation by 3

x2=21/3

x2=7

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

x=±√(,7)

3. Identify the two distinct solutions for the variable x

x=√(,7)

x=−√(,7)

Final Answer

x=±√(,7)
