Answer 6

i is more than just i: i represents the square root of -1, and you do need to know this fact.
\[i=\sqrt{-1}\]

Answer 7

Are you familiar with the FOIL method of multiplying binomials? if so, please multiply out (2-i)(-3+6i). We'll take care of that i^2 later.

Answer 8

Well, let me review the FOIL method.

supposing you wanted to multiply the 2 bionomials (ax+b) and (cx+d) together,
You'd first multiply together the First terms, then the Outer terms, then the Inner terms, and then the Last terms.

Would you please give this a try.
