Question
Add $ \, \color{blue}{ -9x^4+19x^2-8x-12 } \, $ and $ \, \color{orangered}{ -6x }$.
Answer
$$ \left( \color{blue}{-9x^4+19x^2-8x-12} \right) + \left( \color{orangered}{-6x} \right) = -9x^4+19x^2-14x-12 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrrr} & -9x^4 & 19x^2 & -8x & -12 \\ \color{blue}{ + } & & & -6x & \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrrr} & -9x^4 & 19x^2 & -8x & -12 \\ \color{blue}{ + } & & & -6x & \\ \hline & -9x^4 & 19x^2 & -14x & -12 \end{array} $$This page was created using
