$\frac{- x^{3} + 3 x^{2} + 13 x - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 1

Factor $- 1$ out of $- x^{3}$ .

$\frac{- (x^{3}) + 3 x^{2} + 13 x - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 2

Factor $- 1$ out of $3 x^{2}$ .

$\frac{- (x^{3}) - (- 3 x^{2}) + 13 x - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 3

Factor $- 1$ out of $- (x^{3}) - (- 3 x^{2})$ .

$\frac{- (x^{3} - 3 x^{2}) + 13 x - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 4

Factor $- 1$ out of $13 x$ .

$\frac{- (x^{3} - 3 x^{2}) - (- 13 x) - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 5

Factor $- 1$ out of $- (x^{3} - 3 x^{2}) - (- 13 x)$ .

$\frac{- (x^{3} - 3 x^{2} - 13 x) - 15}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 6

Rewrite $- 15$ as $- 1 (15)$ .

$\frac{- (x^{3} - 3 x^{2} - 13 x) - 1 (15)}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 7

Factor $- 1$ out of $- (x^{3} - 3 x^{2} - 13 x) - 1 (15)$ .

$\frac{- (x^{3} - 3 x^{2} - 13 x + 15)}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 8

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- 2 x^{3} + 7 x^{2} + 20 x - 25}$

Step 9

Factor $- 1$ out of $- 2 x^{3}$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3}) + 7 x^{2} + 20 x - 25}$

Step 10

Factor $- 1$ out of $7 x^{2}$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3}) - (- 7 x^{2}) + 20 x - 25}$

Step 11

Factor $- 1$ out of $- (2 x^{3}) - (- 7 x^{2})$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3} - 7 x^{2}) + 20 x - 25}$

Step 12

Factor $- 1$ out of $20 x$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3} - 7 x^{2}) - (- 20 x) - 25}$

Step 13

Factor $- 1$ out of $- (2 x^{3} - 7 x^{2}) - (- 20 x)$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3} - 7 x^{2} - 20 x) - 25}$

Step 14

Rewrite $- 25$ as $- 1 (25)$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3} - 7 x^{2} - 20 x) - 1 (25)}$

Step 15

Factor $- 1$ out of $- (2 x^{3} - 7 x^{2} - 20 x) - 1 (25)$ .

$\frac{- 1 (x^{3} - 3 x^{2} - 13 x + 15)}{- (2 x^{3} - 7 x^{2} - 20 x + 25)}$

Step 16
