Maths module 5?!

I'm sitting my maths module 5 next week and i am seriously stuck on one thing that keeps on coming up on all the past papers :confused:
eg// (5x[squared] -605)/(2x[squared]+22x)

thanks :biggrin:
also sorry about not knowing how to do the squared thing on my keyboard

you would factorise the top and bottom so
5(x^2-121)/2x(x-11)
then you could factorise 5(x^2-121) further to 5(x-11)(x+11)/2x(x-11)
then the (x-11) would cancel out to
5(x+11)/2x
i think this is right
