Answer

x=±2x = \pm 2

Step-by-step solution

2 steps

  1. Divide both sides of the equation by 2.

    2x22=82\frac{2x^2}{2} = \frac{8}{2} x2=4x^2 = 4

  2. Take the square root of both sides to solve for x.

    x2=4\sqrt{x^2} = \sqrt{4} x=±2x = \pm 2

    The solutions are x=2x = 2 and x=−2x = -2.
