    Answer:

    Step-by-step explanation:

    Let the 2 numbers be x and y

    From the problem we have that

    x * y = 600 and x + y = 59

    From x + y = 59 -> x = 59 – y

    Plug x = 59 – y to x * y = 600 we have

    (59 – y) * y = 600

    -> 59y – y^2 = 600

    -> -y^2 + 59y – 600 = 0

    -> y = (59 - \sqrt{1081})/2 or (59 + \sqrt{1081})/2

    Then we could plug the answers in and find x because x = 59 – y
