    multiply numerator and denominator by 3x

    result:

    ( x^2 - 12x)/(15x + 3)

    Ok ive attempted what i think might be an answer...
    x-12
    ----
    3
    ----
    5x+1
    ----
    x

    Right?
    and then i flip flopped it so i could multiply it..
    (x-12) x
    ------ x -----
    3 5x+1
    (the x in the middle symbolizes multiplication)
    so after i multiply them out i get...
    (x^2)-12x
    ---------
    15x +3

    so is that the right answer?
