Answer:

(2x + 28) / (x^2 + 7x + 10)

Explanation:

to subtract, you need to have a common denominator

the easiest way to accomplish this is to multiply each fraction by the "missing" denominators so they match:

[ 8(x+5) / (x+2)(x+5) ] - [ 6(x+2) / (x+2)(x+5) ] =

now that the denominators are the same, you can subtract

8(x+5) - 6(x+2) / (x+2)(x+5)

and simplify:

(8x + 40 - 6x - 12) / (x^2 + 7x + 10)

(2x + 28) / (x^2 + 7x + 10)

that's enough, but you can simplify further:

2(x+14) / (x^2 + 7x + 10)
