find the lcd of this rational algebraic expression 3x+2,2x/x^2-4,x+1/x^2+5x+6 please answer it immidiately i need the answer as soon as possible ..please?

  • math -

    You have listed three "rational algebraic expressions", not one.

    Note that
    (x+1)/(x^2+5x+6) = 1/(x+5)
    and
    2x/(x^2-4) = 2x/[(x+2)(x-2)]

    If you really want a least common denominator, it would be
    [x+2)(x-2)(x+5)
