$18 a x^{2} + 27 a^{2} y - 81 a y^{2}$

Step 1

Factor $9 a$ out of $18 a x^{2}$ .

$9 a (2 x^{2}) + 27 a^{2} y - 81 a y^{2}$

Step 2

Factor $9 a$ out of $27 a^{2} y$ .

$9 a (2 x^{2}) + 9 a (3 a y) - 81 a y^{2}$

Step 3

Factor $9 a$ out of $- 81 a y^{2}$ .

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

Step 4

Factor $9 a$ out of $9 a (2 x^{2}) + 9 a (3 a y)$ .

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

Step 5

Factor $9 a$ out of $9 a (2 x^{2} + 3 a y) + 9 a (- 9 y^{2})$ .

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