$-9m\left(x^{2}+7\right)+4m\left(x^{2}+7\right)$
You asked:
Evaluate the expression: \(-\left( 9 \cdot m\left( {x}^{2} + 7 \right) \right) + 4 \cdot m\left( {x}^{2} + 7 \right)\)
MathBot Answer:
\[-\left( 9 \cdot m\left( {x}^{2} + 7 \right) \right) + 4 \cdot m\left( {x}^{2} + 7 \right) = - 5 m{\left(x^{2} + 7 \right)}\]
