I'm in Acc Math 1, which is basically Honors Algebra 1. I have a quiz tomorrow and I really don't understand what we're learning because my teacher isn't very good.
(3+5i)/2i
(-1+7i)/(3-2i)
(8+3i)/(3-i)
Then, I have an idea about this answer, but I want to make sure I'm doing it correctly.
Find real numbers x and y to make each of the following statements true.
4x-4yi = 1-8i
x=1/4 and y=2
Finally, I know you have to FOIL this problem, but I still can't seem to get a logical answer.
(3-8i)(-6-5i)
I know there are a lot of problems, but even if someone helps me on just one I'll be very grateful. I'm lost, and I feel like I'm the only one in the class who is. Thanks so much!
