Step 1.1

Factor $- 1$ out of $3 u$ .

$\frac{- 8 u^{2} - 8 u + 29}{- 3 u + 7} + \frac{- 8 u^{2} + 7 u - 6}{- (- 3 u) - 7}$

Step 1.2

Rewrite $- 7$ as $- 1 (7)$ .

$\frac{- 8 u^{2} - 8 u + 29}{- 3 u + 7} + \frac{- 8 u^{2} + 7 u - 6}{- (- 3 u) - 1 (7)}$

Step 1.3

Factor $- 1$ out of $- (- 3 u) - 1 (7)$ .

$\frac{- 8 u^{2} - 8 u + 29}{- 3 u + 7} + \frac{- 8 u^{2} + 7 u - 6}{- (- 3 u + 7)}$

Step 1.4

Move a negative from the denominator of $\frac{- 8 u^{2} + 7 u - 6}{- (- 3 u + 7)}$ to the numerator.

$\frac{- 8 u^{2} - 8 u + 29}{- 3 u + 7} + \frac{- (- 8 u^{2} + 7 u - 6)}{- 3 u + 7}$

Step 1.5

Combine the numerators over the common denominator.

$\frac{- 8 u^{2} - 8 u + 29 - (- 8 u^{2} + 7 u - 6)}{- 3 u + 7}$

Step 2.4

Add $- 8 u$ and $0$ .

$\frac{- 8 u + 29 - 7 u + 6}{- 3 u + 7}$

Step 2.5

Subtract $7 u$ from $- 8 u$ .

$\frac{- 15 u + 29 + 6}{- 3 u + 7}$

Step 2.6

Add $29$ and $6$ .

$\frac{- 15 u + 35}{- 3 u + 7}$

Step 2.7
