I'm going to guess what you mean.  You ahve NOT written what I am about to write.

$\dfrac{x-2}{x+3} + \dfrac{10x}{x^{2} - 9}$

Give it another go.  Remember you Order of Operations and use more parentheses.

Factor the denominators.  Where are they zero?

anonymous · Answer

so i factor by the denominators?

tkhunny · Answer

You will need to do that in order to find the Common Denomiator.

anonymous · Answer

so how would i start that?

tkhunny · Answer

Is x + 3 factored?

anonymous · Answer

uhh, yea?

anonymous · Answer

well the common factor would be 1?

tkhunny · Answer

There is no such factor.

Given x + 3 in the denominator, there are two terms, "x" and '3'.  The only FACTOR is "x+3"

Is $x^{2} - 9$ factored?

anonymous · Answer

ohh, no it's not

tkhunny · Answer

You will be factoring it, then.  Identify the factors carefully.
