Question
Answer
$$x^4-6^3+11x^2-8x+2=x^4+11x^2-8x-214$$
Explanation
| $$ \begin{aligned}x^4-6^3+11x^2-8x+2& \xlongequal{ }x^4-216+11x^2-8x+2 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}x^4+11x^2-8x-214\end{aligned} $$ | |
| ① | Combine like terms: $$ x^4 \color{blue}{-216} +11x^2-8x+ \color{blue}{2} = x^4+11x^2-8x \color{blue}{-214} $$ |
