    then
    p^2 -16 p + 64 = 0

  6. (p-8)(p-8) = 0
    p = 8

    y^3/2 = 8
    y^3 = 8*8
    y = 2*2 = 4

  9. Explain:
    I saw (once you fixed it) that the variable at the beginning, y^3 was the square of the one in the middle y^3/2

    So I figured I could make it into a quadratic if I called the 3/2 one p and then the 3 one would be p^2
