Question
Add $ \, \color{blue}{ 4t+8t+9 } \, $ and $ \, \color{orangered}{ 6t+5 }$.
Answer
$$ \left( \color{blue}{4t+8t+9} \right) + \left( \color{orangered}{6t+5} \right) = 18t+14 $$
Explanation
Step 1: First we have to write polynomials in descending order.
$$ \begin{aligned} P(x) &= 12t+9 \\ Q(x) &= 6t+5 \\ \end{aligned} $$Step 2: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 12t & 9 \\ \color{blue}{ + } & 6t & 5 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & 12t & 9 \\ \color{blue}{ + } & 6t & 5 \\ \hline & 18t & 14 \end{array} $$This page was created using
