Factor 15x^2y^4z^5-9z^2

$15 x^{2} y^{4} z^{5} - 9 z^{2}$

Step 1

Factor $3 z^{2}$ out of $15 x^{2} y^{4} z^{5}$ .

$3 z^{2} (5 x^{2} y^{4} z^{3}) - 9 z^{2}$

Step 2

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

$3 z^{2} (5 x^{2} y^{4} z^{3}) + 3 z^{2} (- 3)$

Step 3

Factor $3 z^{2}$ out of $3 z^{2} (5 x^{2} y^{4} z^{3}) + 3 z^{2} (- 3)$ .

$3 z^{2} (5 x^{2} y^{4} z^{3} - 3)$
