Question 280098
You are asked to subtract 2 complex numbers. You have to subtract the real parts
separately from the imaginary parts. I don't know how far you are with
imaginary numbers, but subtract them like this:
{{{2i - 3i = -i}}}
Now subtract the real parts
{{{-5 - 9 = -14}}}
The answer is:
{{{-14 - i}}}
