Add $ \, \color{blue}{ 2x+15+x+x+15+x-5+x+2x-5 } \, $ and $ \, \color{orangered}{ 0 }$.
Answer
$$ \left( \color{blue}{2x+15+x+x+15+x-5+x+2x-5} \right) + \color{orangered}{0} = 8x+20 $$
Explanation
Step 1: First we have to write polynomials in descending order.
$$ \begin{aligned} P(x) &= 8x+20 \\ Q(x) &= 0 \\ \end{aligned} $$Step 2: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 8x & 20 \\ \color{blue}{ + } & & 0 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & 8x & 20 \\ \color{blue}{ + } & & 0 \\ \hline & 8x & 20 \end{array} $$This page was created using
