$40 x^{2} - 100 x y - 80 y^{2}$

Step 1

Factor $20$ out of $40 x^{2}$ .

$20 (2 x^{2}) - 100 x y - 80 y^{2}$

Step 2

Factor $20$ out of $- 100 x y$ .

$20 (2 x^{2}) + 20 (- 5 x y) - 80 y^{2}$

Step 3

Factor $20$ out of $- 80 y^{2}$ .

$20 (2 x^{2}) + 20 (- 5 x y) + 20 (- 4 y^{2})$

Step 4

Factor $20$ out of $20 (2 x^{2}) + 20 (- 5 x y)$ .

$20 (2 x^{2} - 5 x y) + 20 (- 4 y^{2})$

Step 5

Factor $20$ out of $20 (2 x^{2} - 5 x y) + 20 (- 4 y^{2})$ .

$20 (2 x^{2} - 5 x y - 4 y^{2})$
