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?

Answer 1

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)
