SOLUTION: (6-9i)2

Question 401027: (6-9i)2
Answer by jsmallt9(3758) (Show Source): You can put this solution on YOUR website!
I assume the 2 at the end is an exponent. Please use the "^" character to indicate exponents, like this:
(6-9i)^2
Tutors are more likely to help if the problem is clear.

To multiply this we can use FOIL on (6-9i)(6-9i), or we can use the pattern with "a" being 6 and "b" being 9i. I prefer using the pattern:

which simplifies to:

i = so . Substituting -1 for we get:
36-108i+81(-1)
which simplifies as follows:
36-108i+(-81)
-45+108i

P.S. Thanks for your thank you note. It is nice to be appreciated!

As to being paid to help you, I would like very much to do that. But there are complicated issues

How I would be paid
When I would be paid (before or after service)
How we would communicate
- thru Algebra.com, taking advantage of its formula drawing and graphing facilities but raising the possibility that you would get free help from someone else before I could respond; or
- directly via email and not have the formula drawing and graphing facilities.

which would make it very difficult for us to work something out with which we could both be happy.

I suggest that you check out the ads on Algebra.com. Many of them are about about paid tutoring. Maybe one of those would be of help to you.
