$3 z^{4} - 15 z^{3} - 9 z^{2}$

Step 1

Factor $3 z^{2}$ out of $3 z^{4}$ .

$3 z^{2} (z^{2}) - 15 z^{3} - 9 z^{2}$

Step 2

Factor $3 z^{2}$ out of $- 15 z^{3}$ .

$3 z^{2} (z^{2}) + 3 z^{2} (- 5 z) - 9 z^{2}$

Step 3

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

$3 z^{2} (z^{2}) + 3 z^{2} (- 5 z) + 3 z^{2} (- 3)$

Step 4

Factor $3 z^{2}$ out of $3 z^{2} (z^{2}) + 3 z^{2} (- 5 z)$ .

$3 z^{2} (z^{2} - 5 z) + 3 z^{2} (- 3)$

Step 5

Factor $3 z^{2}$ out of $3 z^{2} (z^{2} - 5 z) + 3 z^{2} (- 3)$ .

$3 z^{2} (z^{2} - 5 z - 3)$
