Divide 25 in two parts such that its product is 126

  • math -

    One part must be a multiple of 2 to get the even number. I worked up the even numbers to get the product you indicate, but the closest I could get was 8*17 = 136.

    Do you have a typo?

  • math -

    its a question involving simultaneous equations.

    1) xy = 126

    2) x+ y = 25

    Inserting 2) into 1):

    (25-x)x = 126

    -x^2 +25x-126 = 0

    Use the ABC formula, and you get

    x= 18 or x = 7

    and that is the answer,
    because 18 + 7 is 25 and 18 x 7 =126.
