Question

How do you add `\frac { 3x - 4} { x ^ { 2} - 9} + \frac { 7x - 3} { x ^ { 2} - 9}`?

Answer 1

`(10x - 7)/(x^2 -9)`

Explanation:

Since you have a common denominator, all you need to do is combine like terms in both numerators, and keep the same denominator. The answer cannot be reduced, since there are no common factors.
