Question

What are the correct steps for solving the equation 9x^2=108?

A. X^2= 99

Answer 1

x=sqrt of 12

Explanation:

First, you divide by 9 on both sides:

x^2= 108/9

Then you solve that:

x^2 = 12

Then you find the root of both sides:

sqrt (x^2)= sqrt (12)

and you get:

x= sqrt of 12 which is about 3.46... OR 2√3
