    x = 3±sqrt (20)

    Step-by-step explanation:

    (x-3) ^2-20=0

    Add 20 to each side

    (x-3) ^2-20+20=0+20

    (x-3) ^2=20

    Take the square root of each side

    sqrt ((x-3) ^2) = ±sqrt (20)

    (x-3) = ±sqrt (20)

    Add 3 to each side

    x-3+3 = 3±sqrt (20)

    x = 3±sqrt (20)
