Question

Which shows the expression x^2-1/x^2-x

Answer 1

its b on edge 2021

Explanation:

Answer 2

`\large\boxed{(x^2-1)/(x^2-x)=(x+1)/(x)=1+(1)/(x)}`

Explanation:

`(x^2-1)/(x^2-x)=(x^2-1^2)/(x(x-1))\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=((x-1)(x+1))/(x(x-1))\qquad\text{cancel}\ (x-1)\\\\=(x+1)/(x)=(x)/(x)+(1)/(x)=1+(1)/(x)`
