-10-6i / -9+9i
multiply top and bottom by -9-9i, Note that
(-9+9i)(-9-9i) = 9^2+9^2 = 162
So, you have
(-10-6i)(-9-9i)/162
Now just do the multiplication and put into standard form.
(-9+9i)(-9-9i) = 9^2+9^2 = 162
So, you have
(-10-6i)(-9-9i)/162
Now just do the multiplication and put into standard form.
