Answer:

x = 8

Step-by-step explanation:


(3x^2)/(4) =48

multiply both sides by 4:
3x^2=192

divide both sides by 3:
x^2=64

take the square root:


√(x^2) = √(64) \\x=8

3x^2 / 4 = 48

Multiply both sides by 4 to get rid of the four on the left.

3x^2 = 192

Divide both sides by 3

x^2 = 64

The square root 64 to get x

Remember there are two answers

x = 8 and x = -8
