Question

subtract

x^2-1/x^2-x-2 - x-1/x-2

Answer 1

factorize \[x^2-1\]
and \[x^2-x-2\]

Answer 2

so it would be

x-1/x-2??

Answer 3

the answer i mean

Answer 4

no \[x^2-1= (x-1)(x+1)\]
and \[x^2-x-2 = x^2 - 2x + x -2 = x(x-2) + 1(x-2)= (x+1)(x-2)\]
so your problem is
\[{{x^2-1}\over{x^2-x-2}}-{{x-1}\over{x-2}}= {{(x-1)(x+1)}\over{(x+1)(x-2)}} - {{x-1}\over{x-2}} = {{x-1}\over{x-2}}-{{x-1}\over{x-2}}=0\]

Answer 5

so the answer is 0

Answer 6

oh ok it got it!

Answer 7

yeah buddy you were right
