    12x = 32 + x^2

    => x^2 - 12x + 32 = 0

    => x^2 - 8x - 4x + 32 = 0

    => x(x - 8) - 4(x - 8) = 0

    => (x - 8)(x - 4) = 0

    => x - 8 = 0 or x - 4 = 0

    => x = 8 or x = 4 Ans.

    Subtract 12x from both sides:

    0 = x^2 - 12x + 32

    Factor to:

    0 = (x - 4)(x - 8)

    Solutions are x = 4 and x = 8

    first bring 12x to the other side

    so it would be

    0=x^2-12x+32

    then use the quadratic formula

    move 12x to the other side and equal it all to zero. Hope I helped. Xx. Your answer should be ---> (x-8)(x-4)
