Question
Multiply polynomial $ \, \color{blue}{ n+15 } \, $ by $ \, \color{orangered}{ 2n^2 }$.
Answer
$$ \left( \color{blue}{n+15} \right) \cdot \color{orangered}{2n^2} = 2n^3+30n^2 $$
Explanation
We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \left( n+15 \right) \cdot \color{orangered}{2n^2} &= n \cdot \color{orangered}{2n^2} + 15 \cdot \color{orangered}{2n^2} = \\ &= 2n^3+30n^2 \end{aligned} $$This page was created using
