`lim x->oo (x^2 + 2)/(x-1)`

`or, lim x->oo (2x)/1`

`or, lim x-> (2x) = oo`

Plug in `oo ` everywhere you have x
`lim_(x->oo)(oo^2+2)/(oo-1)=oo/oo `

Since you have , you can use L^Hopital's Rule and differentiate the numerator and denominator independently.

`lim_(x->oo)2x=oo `

Therefore,

the `lim_(x->oo)(x^2+2)/(x-1)=oo `
