प्रश्न

Evaluate the following limits:

`lim_(x  -> oo) 3/(x - 2) - (2x + 11)/(x^2 + x - 6)`

योग

उत्तर

`lim_(x  -> oo) 3/(x - 2) - (2x + 11)/(x^2 + x - 6) =  lim_(x -> oo) (3/(x - 2) - (2x + 11)/((x + 3)(x - 2)))`

= `lim_(x -> oo) (3(x + 3) - (2x + 11))/((x + 3)(x - 2))`

= `lim_(x -> oo) (3x + 9 - 2x - 11)/((x + 3)(x - 2))`

= `lim_(x -> oo) (x - 2)/((x + 3)(x - 2))`

= `lim_(x -> oo) 1/(x + 3)`

= `1/oo`

`lim_(x  -> oo) 3/(x - 2) - (2x + 11)/(x^2 + x - 6)` = 0
