Question 904021: Hi there, I'm stuck on how to FOIL this problem and have tried it a few different times. Could you help me with this, please?
+%289+%2B+1i%29%289-5i%29-%286%2B4i%29%286-4i%29+ Directions: Express result in standard form.
I'm aware of how to put the numbers into standard form after FOILing, but not sure how to distribute the - sign to (6+4i)(6-4i)
Thank you!
