Question

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?

Answer 1

(x-2)/x

Answer 2

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.

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

in which case the answer should be:

x(x+5)(x-5)(x+2)

is that an option?

Answer 8

Yes! Thanks so much! :D

Answer 9

no prob :)
