$30 y^{3 \sqrt{y - 1}} - 105 y^{2 \sqrt{y - 1}} + 45 y \sqrt{y - 1}$

Step 1

Factor $15$ out of $30 y^{3 \sqrt{y - 1}}$ .

$15 (2 y^{3 \sqrt{y - 1}}) - 105 y^{2 \sqrt{y - 1}} + 45 y \sqrt{y - 1}$

Step 2

Factor $15$ out of $- 105 y^{2 \sqrt{y - 1}}$ .

$15 (2 y^{3 \sqrt{y - 1}}) + 15 (- 7 y^{2 \sqrt{y - 1}}) + 45 y \sqrt{y - 1}$

Step 3

Factor $15$ out of $45 y \sqrt{y - 1}$ .

$15 (2 y^{3 \sqrt{y - 1}}) + 15 (- 7 y^{2 \sqrt{y - 1}}) + 15 (3 y \sqrt{y - 1})$

Step 4

Factor $15$ out of $15 (2 y^{3 \sqrt{y - 1}}) + 15 (- 7 y^{2 \sqrt{y - 1}})$ .

$15 (2 y^{3 \sqrt{y - 1}} - 7 y^{2 \sqrt{y - 1}}) + 15 (3 y \sqrt{y - 1})$

Step 5

Factor $15$ out of $15 (2 y^{3 \sqrt{y - 1}} - 7 y^{2 \sqrt{y - 1}}) + 15 (3 y \sqrt{y - 1})$ .

$15 (2 y^{3 \sqrt{y - 1}} - 7 y^{2 \sqrt{y - 1}} + 3 y \sqrt{y - 1})$
