Step 1.1

Factor $5$ out of $20 y^{2}$ .

$5 (4 y^{2}) - 45 \div 10 y^{2} - 5 y - 15$

Step 1.2

Factor $5$ out of $- 45 \div 10 y^{2}$ .

$5 (4 y^{2}) + 5 (- \frac{9}{10 y^{2}}) - 5 y - 15$

Step 1.3

Factor $5$ out of $- 5 y$ .

$5 (4 y^{2}) + 5 (- \frac{9}{10 y^{2}}) + 5 (- y) - 15$

Step 1.4

Factor $5$ out of $- 15$ .

$5 (4 y^{2}) + 5 (- \frac{9}{10 y^{2}}) + 5 (- y) + 5 (- 3)$

Step 1.5

Factor $5$ out of $5 (4 y^{2}) + 5 (- \frac{9}{10 y^{2}})$ .

$5 (4 y^{2} - \frac{9}{10 y^{2}}) + 5 (- y) + 5 (- 3)$

Step 1.6

Factor $5$ out of $5 (4 y^{2} - \frac{9}{10 y^{2}}) + 5 (- y)$ .

$5 (4 y^{2} - \frac{9}{10 y^{2}} - y) + 5 (- 3)$

Step 1.7

Factor $5$ out of $5 (4 y^{2} - \frac{9}{10 y^{2}} - y) + 5 (- 3)$ .

$5 (4 y^{2} - \frac{9}{10 y^{2}} - y - 3)$

Step 2
