Question

Two rational expressions have denominators of 2x + 3 and 3 + 2x. Can you find their sum by simply adding their numerators and placing the sum over 2x + 3? Explain.

Answer 1

Okay i haven't done this years but base on my knowledge it think that the answer is 6 and that because:
(2x+3) + (3-2x)
(2x+2x+3) +(3-2x+2x)      (what ever you to one side you do the next and that why it cancel each other)
3+3=6
that my explanation hope this help
