You're missing a negative sign

$\displaystyle \frac{6-6i}{-9i}=\frac{2-2i}{-3i}=\frac{2-2i}{-3i}\cdot \frac{i}{i}=\frac{2i-2i^2}{-3i^2}=\frac{2i+2}{3}$

EDIT: My bad I read the question wrong. I have edited my answer accordingly. - Mar 23rd 2013, 08:29 AMSorobanRe: imaginary numbers

Your answer, $\displaystyle \tfrac{2}{3} + \tfrac{2}{3}i$, is correct.

If you entered your answer as**2/3 + 2/3i**,

. . it might be read as: $\displaystyle \tfrac{2}{3} + \tfrac{2}{3i}$

Try entering it as.**2/3 + 2i/3**. or .**2/3 + (2/3)i**.
