Question

which expression represents x^2-3x-10 over x^2-25

Answer 1

Options please

Answer 2

x-5 is the answer i think!

Answer 3

that is the only expression that is in common for both the expressions!

Answer 4

(x^2-3x-10)=(x-5)(x+2)
(x^2-25)=(x-5)(x-5)
So divide them and get your answer

Answer 5

or x-2 over x-5

Answer 6

x^2-3x-10/x^2-25
=(x^2+2x-5x-10)/(x-5)(x+5)
=x(x+2)-5(x+2)/(X-5)(X+5)
=(x-5)(x+2)/(x-5)(x+5)
=(x+2)/(x+5)

Answer 7

its x-5

Answer 8

no it's (x+2)/(x+5)

Answer 9

i got but i ot sure

Answer 10
