Please help! Given x^2-4/x^2+5x * x^2-25/x^2-3x-10, perform the indicated operation and simplify the result. The denominator of the second step is?

Question

anonymous · Answer

(x-2)/x

anonymous · Answer

x(x + 5)2(x - 2)
		
x(x + 5)(x - 5)(x - 2)
		
x(x + 5)(x - 5)(x + 2)
		
(x + 1)(x + 5)(x - 5)(x + 2)
These are the options :/ I'm just not sure how to figure it out.

anonymous · Answer

what... those make no sense.. given what you gave me... the answer should be (x-2)/x

anonymous · Answer

Hmm. O.k. I'll figure it out :) Thanks for your help!

anonymous · Answer

Wait I min.. i'll try to see the question was worded weirdly..

anonymous · Answer

I think the question doesn't need simplification.. it just wants the denominator.

anonymous · Answer

in which case the answer should be:

x(x+5)(x-5)(x+2)

is that an option?

anonymous · Answer

Yes! Thanks so much! :D
