hi, could someone check the answers of these for me? btw, the book says that they are all wrong. i dont understand why.
1. If z = 2 + i, evaluate:
a) 3z = 6 + 3i
2. Solve for z; expressing answers in the form a + ib
b) Totally clueless about this one:
Solve for x.
I got 3i/2. but the answer is -3i/2. I dont get why.
