    x=±3 sqrt (2)

    Step-by-step explanation:

    3x^2 - 6 = 48

    Add 6 to each side

    3x^2 - 6+6 = 48+6

    3x^2 = 54

    Divide each side by 3

    3x^2/3 = 54/3

    x^2 = 18

    Take the square root of each side

    sqrt (x^2) = sqrt (18)

    x = sqrt (18)

    We know sqrt (ab) = sqrt (a) sqrt (b)

    x = sqrt (9) sqrt (2)

    x=±3 sqrt (2)
