Which statement describes how to solve ^3 squareroot x^2-6 = ^3 square root 2x+2

Cube both sides and then solve the resulting quadratic equation.

Step-by-step explanation:

It's the answer on edge

Square both sides and then solves the resulting quadratic equations

Step-by-step explanation:

The equation is 3sqrt (x^2-6) = 3sqrt (2x+2)

We can solve this by;

First square both sides;

(3√ (x²-6)) ² = (3√ (2x+2)) ²

We obtain;

9 (x²-6) = 9 (2x+2)

We simplify to obtain a quadratic equation;

x²-6=2x+2

= x²-2x-8=0

Then we solve the quadratic equation;

x²-4x+2x-8=0

x (x-4) + 2 (x-8) = 0

(x+2) (x-8) = 0

Values of x = - 2 or 8
