Factor -15x^3y^4z^2-3xz^5

$- 15 x^{3} y^{4} z^{2} - 3 x z^{5}$

Step 1

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

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

Step 2

Factor $- 3 x z^{2}$ out of $- 3 x z^{5}$ .

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

Step 3

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

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