Add $ \, \color{blue}{ 9+500 } \, $ and $ \, \color{orangered}{ 2x+5 }$.
Answer
$$ \left( \color{blue}{9+500} \right) + \left( \color{orangered}{2x+5} \right) = 2x+514 $$
Explanation
Step 1: First we have to write polynomials in descending order.
$$ \begin{aligned} P(x) &= 509 \\ Q(x) &= 2x+5 \\ \end{aligned} $$Step 2: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & & 509 \\ \color{blue}{ + } & 2x & 5 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & & 509 \\ \color{blue}{ + } & 2x & 5 \\ \hline & 2x & 514 \end{array} $$This page was created using
