 P: 3 If i have something like (6/x+2) + (8/x+3) how to i do that? aren't i supposed to invert and multiply or something, thanks --Val
 P: n/a $$\frac{6(x+3)}{(x+2)(x+3)} + \frac{8(x+2)}{(x+2)(x+3)}$$ You just need to find a common denominator.

That's for division by a fraction, in which case you multiply by the reciprocal.

Since the two denominators are x+2 and x+3 the common denominator will be (x+2)(x+3).

It's just like 1/2+ 1/3= (1/2)(3/3)+ (1/3)(2/2)= 3/6+ 2/6= 5/6.
