$9 b (9 b + 7 a) - 5 a (9 b + 7 a) - 8 (9 b + 7 a)$

Step 1

Factor $9 b + 7 a$ out of $9 b (9 b + 7 a)$ .

$(9 b + 7 a) (9 b) - 5 a (9 b + 7 a) - 8 (9 b + 7 a)$

Step 2

Factor $9 b + 7 a$ out of $- 5 a (9 b + 7 a)$ .

$(9 b + 7 a) (9 b) + (9 b + 7 a) (- 5 a) - 8 (9 b + 7 a)$

Step 3

Factor $9 b + 7 a$ out of $- 8 (9 b + 7 a)$ .

$(9 b + 7 a) (9 b) + (9 b + 7 a) (- 5 a) + (9 b + 7 a) \cdot - 8$

Step 4

Factor $9 b + 7 a$ out of $(9 b + 7 a) (9 b) + (9 b + 7 a) (- 5 a)$ .

$(9 b + 7 a) (9 b - 5 a) + (9 b + 7 a) \cdot - 8$

Step 5

Factor $9 b + 7 a$ out of $(9 b + 7 a) (9 b - 5 a) + (9 b + 7 a) \cdot - 8$ .

$(9 b + 7 a) (9 b - 5 a - 8)$
