Question
Answer
$$3i+4-3i+2i-6=2i-2$$
Explanation
| $$ \begin{aligned}3i+4-3i+2i-6& \xlongequal{ } \cancel{3i}+4 -\cancel{3i}+2i-6 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}2i-2\end{aligned} $$ | |
| ① | Combine like terms: $$ \, \color{blue}{ \cancel{3i}} \,+ \color{green}{4} \, \color{orange}{ -\cancel{3i}} \,+ \color{orange}{2i} \color{green}{-6} = \color{orange}{2i} \color{green}{-2} $$ |
