    Steps to solve:

    2x² = 8

    ~Divide 2 to both sides

    2x²/2 = 8/2

    ~Simplify

    x² = 4

    ~Take the square root of both sides

    ±√x² = ±√4

    ~Simplify

    x = 2 or x = - 2

    x = ±2

    Step-by-step explanation:

    2x^2 = 8

    Divide each side by 2

    2x^2/2 = 8/2

    x^2 = 4

    Take the square root of each side

    sqrt (x^2) = ±sqrt (4)

    x = ±2
