    2 (5x + 2) ^2 = 48

    divide both sides by 2

    (5x + 2) ^2 = 24

    square root both sides to clear the power of two.

    5x + 2 = + - sqrt24

    subtract 2 from both sides

    5x = - 2 + - sqrt 24

    divide both sides by 5

    x = (-2 + - sqrt24) / 5 or decimal answers. 58 and - 1.38
