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