Question
Multiply polynomial $ \, \color{blue}{ 5+7 } \, $ by $ \, \color{orangered}{ 8r-2 }$.
Answer
$$ \left( \color{blue}{5+7} \right) \cdot \left( \color{orangered}{8r-2} \right) = 96r-24 $$
Explanation
Step 1: First we have to write polynomials in descending order.
$$ \begin{aligned} P(x) &= 12 \\ Q(x) &= 8r-2 \\ \end{aligned} $$We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \color{blue}{12} \cdot \left( 8r-2 \right) &= \color{blue}{12} \cdot 8r + \color{blue}{12} \cdot \left( -2\right) = \\ &= 96r-24 \end{aligned} $$This page was created using
