Question

PLSSSSS HELLLLLLP!!!!!

Answer 1

`(3n^2-7n+15)/((n+3)(n-4))` will be the answer.

Explanation:

The given expression is,

`(3n)/((n+3))+(5)/((n-4))`

By solving this expression,

`(3n)/((n+3))+(5)/((n-4))`

=
`(3n(n-4))/((n+3)(n-4))+(5(n+3))/((n+3)(n-4))`

=
`(3n(n-4)+5(n+3))/((n+3)(n-4))`

=
`(3n^2-12n+5n+15)/((n+3)(n-4))`

=
`(3n^2-7n+15)/((n+3)(n-4))`

Therefore, fraction given in option (2) will be the answer.
