Multiply polynomial $ \, \color{blue}{ -7x } \, $ by $ \, \color{orangered}{ -10x-9 }$.
Answer
$$ \color{blue}{-7x} \cdot \left( \color{orangered}{-10x-9} \right) = 70x^2+63x $$
Explanation
We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \color{blue}{-7x} \cdot \left( -10x-9 \right) &= \color{blue}{-7x} \cdot \left( -10x\right) + \color{blue}{-7x} \cdot \left( -9\right) = \\ &= 70x^2+63x \end{aligned} $$This page was created using
