Plus or minus 3. (The 1st answer)

x^2 means (-3*-3) which equals 9

x^2 means (3838) which also equals 9

6*9=54

First u would divide by 6 on both sides to get the x by itself and you would get x squared is equal to 9. Then u would take the sqaure root of both sides because u want to get rid of the squared and a sqaure root un do's that. After square rooting both sides you would get x = 3 because the square root of x squared is x and the square root of 9 is 3. so the answer is Plus or minus 3 or the first choice. Its also plus or minus because two negative 3's would give you nine and two positive 3's would give u 9.
