You could use synthetic division or polynomial long division.

Explanation:

The formatting is hard for me to write on this. However, Khan academy has an excellent and short video on how you could do a problem like this using synthetic division, which is a much easier and more efficient way of doing these kinds of problems. Synthetic Division Tutorial

$x - 8 + \frac{2}{x + 1}$ $x-8+2/(x+1)$

Explanation:

$\frac{x}{x + 1} \frac{x - 8 - 7}{) x^{2} - 7 x - 6}$ $color(white)((x)/color(black)(x+1))(x-8color(white)(-7))/(")"x^2-7x-6)$
$5 \frac{- (x^{2} - x)}{17886770 - 8 x - 6}$ $color(white)(5)(-(x^2-x))/(color(white)(17886770)color(white)()-8x-6)$
$- 1 \times 1 \frac{- (- 8 x - 8)}{- \times \times \times 2}$ $color(white)(-1xx1)(-(-8x-8))/(color(white)(-xxxxxx)2)$
