Question

Evaluate the following limits, if necessary use l’Hôpital Rule:

`lim_(x - oo) (2x^2 - 3)/(x^2 -5x + 3)`

Sum

Solution

`lim_(x - oo) (2x^2 - 3)/(x^2 -5x + 3)`  .......`[oo/oo  "Indeterminate form"]`

Applying L' Hôpital's rule,

= `lim_(x -> oo) (4x)/(2x - 5)`  ........`[oo/oo  "Indeterminate form"]`

= `lim_(x -> oo) 4/2`  ........[Applying L' Hôpital's rule]

= 2
