Answer:

• a = 3
• b = -18

Explanation:

Using the least common denominator, we have ...

`2-(x+1)/(x-2)-(x-4)/(x+2)\\\\=(2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2))/((x-2)(x+2))\\\\=(2(x^2-4)-(x^2+3x+2)-(x^2-6x+8))/(x^2-4)\\\\=((2-1-1)x^2+(-3+6)x+(-8-2-8))/(x^2-4)=\boxed{(3x-18)/(x^2-4)}`

The values of a and b are ...

a = 3

b = -18
