Add like terms that are in the bottom first

I know once you subtract below and do the top it becomes 3i/-2-i

and then multiply it by its conjugate +2+i right on both sides?

then multiply the top and the bottom with the conjugate of -2-i, the conjugate is -2+i

oh okay that's where I was wrong

You just change the sign that is before the i/square root

3 goes into -3-6i = the final answer is -1 - 2i

no problem!!! :)

oh hey could you help me with one more problem I need to double-check?

sure I will if I can!! :)
