Answer 1

`x^2+2x-8` is equal to (x-2)(x+4)

So you need to multiply the fraction on the right by (x+4) to get the

Lowest common denominator of
`x^2+2x-8`

Multiplying the right fraction would get you
`(2x+8)/(x^2+2x-8)`

Then, adding both fractions gets you:

`(3 + 2x + 8)/(x^2+2x-8)`

The simplest form of the rational
`(2x+11)/(x^2+2x-8)`

And the excluded values would be -4, 2
