In the attachment, you wrote the divisor as 'x' instead of 'x - 2' in the first line, which is incorrect.
 
so other than that my working is ok?
 
You can always check your work by multiplying the quotient by the divisor and adding any remainder, to see if you obtain the original dividend.
 
ah right that's what I have done on the bottom of the worksheets thanks :)
