Question
Multiply polynomial $ \, \color{blue}{ -2m } \, $ by $ \, \color{orangered}{ -4m^2-5 }$.
Answer
$$ \color{blue}{-2m} \cdot \left( \color{orangered}{-4m^2-5} \right) = 8m^3+10m $$
Explanation
We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \color{blue}{-2m} \cdot \left( -4m^2-5 \right) &= \color{blue}{-2m} \cdot \left( -4m^2\right) + \color{blue}{-2m} \cdot \left( -5\right) = \\ &= 8m^3+10m \end{aligned} $$This page was created using
