Question
Answer
$$1^4-8\cdot1^3+5\cdot1^2+14\cdot1=12$$
Explanation
| $$ \begin{aligned}1^4-8\cdot1^3+5\cdot1^2+14\cdot1& \xlongequal{ }1-8\cdot1+5\cdot1+14\cdot1 \xlongequal{ } \\[1 em] & \xlongequal{ }1-8+5+14 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}12\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{1} \color{red}{-8} + \color{green}{5} + \color{green}{14} = \color{green}{12} $$ |
