Hmm, so do you know how to get a common denominator?

aripotta · Answer

i was thinking just like, subtract 3?? to make it x - 3, but then 3 - 3 = 0 so that wouldn't work out right...

parthkohli · Answer

Go back to the basics ;-)$$\dfrac{3\color{#C00}{\left(x-3\right)}}{x\color{#C00}{(x - 3)}} + \dfrac{13\color{#C00}x}{\color{#C00}{x}(x - 3)}$$Did you get how I did that?

aripotta · Answer

hmm...ok...

parthkohli · Answer

Eh? You gotta be sure... it's kinda my duty to explain it to you

aripotta · Answer

yea, i get it :] thanks

parthkohli · Answer

Err, fine lol. So you got the same denominators: $x(x  -3)$. Can you add the numerators?

aripotta · Answer
