I imagine plenty of people want help with their math homework. I am three of them. To start out with:
21. 2/(3-i)
I know how to do this one and have done similar questions successfully, but the answer I keep getting isn't the right one, which is (3/5) + (1/5)i.
35. (-3 - √-7) ^2
Same thing. I know how to do it, but I'm not getting the right answer (2 + 6i√7)
(2/(9(x+h)^2)) - 2/(9x^2))/h
I got nothing on this.
