+658 Hey I'm in Honors Geometry let us try some algebra II!
Rectangular form is \(a + bi\) according to https://www.youtube.com/watch?v=o0b1dSn_yNY
I learned from this video https://www.youtube.com/watch?v=a6RL2vmmPOU to do the following:
\(\frac{15 + 10i}{1+2i}*\frac{1-2i}{1-2i}=\frac{15+10i-30i+20}{1-2i^2}=\frac{35-20i}{3}\)
