Factor 36x^4y^4z^4-20x^8y

$36 x^{4} y^{4} z^{4} - 20 x^{8} y$

Step 1

Factor $4 x^{4} y$ out of $36 x^{4} y^{4} z^{4}$ .

$4 x^{4} y (9 y^{3} z^{4}) - 20 x^{8} y$

Step 2

Factor $4 x^{4} y$ out of $- 20 x^{8} y$ .

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

Step 3

Factor $4 x^{4} y$ out of $4 x^{4} y (9 y^{3} z^{4}) + 4 x^{4} y (- 5 x^{4})$ .

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