Answer 2

Here,

• For subtracting $\rm {m}^{2} - 2 \:$ from $\rm{} { - 3m}^{2} + 2m + 9$,

We Need To Know,

$\bullet \: \boxed{( \red+ ) \times ( \red+ ) = \purple +} \\ \bullet \:\boxed{( \red - ) \times ( \red+ ) = \purple - } \\\bullet \: \boxed{( \red+ ) \times ( \red - ) = \purple - } \\ \bullet \:\boxed{( \red - ) \times ( \red - ) = \purple + }$

Now,

$\green = \pink > \rm{}{ - 3m}^{2} + 2m + 9 - ( {m}^{2} - 2 ) \\ \green = \pink> \rm{} { - 3m}^{2} + 2m + 9 - {m}^{2} + 2 \\\green = \pink> \rm \underline{ { \: - 4m}^{2} + 2m + 11 \: \: }$

Hence,

• On subtracting $\rm {m}^{2} - 2 \:$ from $\rm{} { - 3m}^{2} + 2m + 9$, we get $\rm({ { \: - 4m}^{2} + 2m + 11 \: \: })$.
