Expressing in the from a+jb?

I need to express this in the form a + jb. I tried to rationalise the denominator to end up with j on the top of the fraction only using (1-jwCR) to multiply top and bottom and I ended up with the following:

Could anyone confirm or help with getting the correct answer and is there any way to simplify this further?

Thank you for help.

you could simplify it a bit if you chose to

$\dfrac{R}{1+(\omega R C)^2}\left(1 -j \omega R C\right)$
