Factor Completely $250 k^{3} m-16 m^{4}$ A) $2 \mathrm{~m}(5 \mathrm{k}-2 \mathrm{~m})\left(25 \mathrm{k}^{2}+10 \mathrm{~km}+4 \mathrm{~m}^{2}\right)$

Multiple Choice

Factor completely. If the polynomial cannot be factored, write "prime."
- $250 k^{3} m-16 m^{4}$

A) $2 \mathrm{~m}(5 \mathrm{k}-2 \mathrm{~m}) \left(25 \mathrm{k}^{2}+10 \mathrm{~km}+4 \mathrm{~m}^{2}\right)$
B) $\left(10 \mathrm{~km}-4 \mathrm{~m}^{2}\right) \left(25 \mathrm{k}^{2}+4 \mathrm{~m}^{2}\right)$
C) $2 \mathrm{~m}\left(5 \mathrm{k}+2 \mathrm{~m}^{2}\right) \left(25 \mathrm{k}^{2}-10 \mathrm{~km}+4 \mathrm{~km}^{2}\right)$
D) $2 \mathrm{~m}(125 \mathrm{k}-2 \mathrm{~m}) \left(\mathrm{k}^{2}+10 \mathrm{~km}+4 \mathrm{~m}^{2}\right)$
