A) $9 m^{4}+6 m^{3}+9 m^{2}$
B) $10 m^{4}-6 m^{3}+9 m^{2}$
C) $-9 m^{4}-6 m^{3}-9 m^{2}$
D) $9 m^{8}+6 m^{6}+9 m^{2}$

Question

Quizplus · Accepted Answer

To collect like terms, combine coefficients of terms with the same exponent: $10m^{4}-m^{4}=9m^{4}$, $m^{3}+5m^{3}=6m^{3}$, and the $9m^{2}$ term remains unchanged, resulting in $9m^{4}+6m^{3}+9m^{2}$.
