    x = - 9 x = 1

    Step-by-step explanation:

    1/4 (x+5) ^2-1=3

    Add 1 to each side

    1/4 (x+5) ^2-1+1=3+1

    1/4 (x+5) ^2=4

    Multiply each side by 4

    4*1/4 (x+5) ^2=4*4

    (x+5) ^2=16

    Take the square root of each side

    sqrt ((x+5) ^2) = ±sqrt (16)

    x+5 = ±4

    Subtract 5 from each side

    x+5-5 = - 5±4

    x = - 5±4

    x = - 5-4 x = - 5+4

    x = - 9 x = 1
