Simple Complex question

I have to state clearly the real and imaginary parts of that. But I can only get the answer to be 6. Is the question just being an arse and trying to trick me, or is there an Imaginary part?

realise the denominator but multiplying by 2+3i and 2-3i

So im(z) = 0 ?

nm - wrote the question down wrong

edit - yep, answer is 6, so the imaginary part is zero.

Well if you get no imaginary part yes. I was working it out but I've run out of space on the small piece of paper I have and made a mistake.

I'll show the working hold on.

Yep the answer is 6, just worked it out.

Im(z) = 0

Damn, pencil, paper, and scan is far quicker than awkward symbol typing on awkward maths tool

buutttt, LOL how did you screw up 2*2???
