[tex]\frac{x}{x^2-9} - \frac{1}{2x-6}[/tex]
When I first worked this problem I found the answer to be:
[tex]\frac{1}{2x-6}[/tex]
However, in my English class we had this Vietnamese substitute who took my worksheet and did the problems on it in his head and pointed at the answer I wrote for this problem and walked away. He came back and worked it out in front of me and he got the answer:
[tex]\frac{1}{2x+6}[/tex]
Which answer is correct?
