Write the complex number in the form a + bi.
[1 + sq rt (-2)] * [2 + sq rt (-4)]
The answer I get is:
2 + 2*sq rt(2) + [2 + 2*sq rt(2)]i
The answer in the book is:
[2 - 2*sq rt(2)] + [2 + 2*sq rt(2)]i
I'm sorry if my typing is confusing. I don't know how to type the math symbols.
Thanks for any help.
