$3 a^{3} - 9 a^{2} b + 9 a b^{2} - 3 b^{2}$

Step 1

Factor $3$ out of $3 a^{3}$ .

$3 (a^{3}) - 9 a^{2} b + 9 a b^{2} - 3 b^{2}$

Step 2

Factor $3$ out of $- 9 a^{2} b$ .

$3 (a^{3}) + 3 (- 3 a^{2} b) + 9 a b^{2} - 3 b^{2}$

Step 3

Factor $3$ out of $9 a b^{2}$ .

$3 (a^{3}) + 3 (- 3 a^{2} b) + 3 (3 a b^{2}) - 3 b^{2}$

Step 4

Factor $3$ out of $- 3 b^{2}$ .

$3 (a^{3}) + 3 (- 3 a^{2} b) + 3 (3 a b^{2}) + 3 (- b^{2})$

Step 5

Factor $3$ out of $3 (a^{3}) + 3 (- 3 a^{2} b)$ .

$3 (a^{3} - 3 a^{2} b) + 3 (3 a b^{2}) + 3 (- b^{2})$

Step 6

Factor $3$ out of $3 (a^{3} - 3 a^{2} b) + 3 (3 a b^{2})$ .

$3 (a^{3} - 3 a^{2} b + 3 a b^{2}) + 3 (- b^{2})$

Step 7

Factor $3$ out of $3 (a^{3} - 3 a^{2} b + 3 a b^{2}) + 3 (- b^{2})$ .

$3 (a^{3} - 3 a^{2} b + 3 a b^{2} - b^{2})$
