HAYESxELITE 3 years ago subtract x^2-1/x^2-x-2 - x-1/x-2

1. sheg

factorize $x^2-1$ and $x^2-x-2$

2. HAYESxELITE

so it would be x-1/x-2??

4. sheg

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 ${{x^2-1}\over{x^2-x-2}}-{{x-1}\over{x-2}}= {{(x-1)(x+1)}\over{(x+1)(x-2)}} - {{x-1}\over{x-2}} = {{x-1}\over{x-2}}-{{x-1}\over{x-2}}=0$
