lim(xtooo) ((x^(3))/(3x^(2)-4)-(x^(2))/(...

`lim_(xtooo) ((x^(3))/(3x^(2)-4)-(x^(2))/(3x+2))" is equal to "`

A

`2`

B

`-1`

C

`0`

D

`2/9`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset(xtooo)lim((x^(3))/(3x^(2)-4)-(x^(2))/(3x+2))=underset(xtooo)lim(x^(3)(3x+2)-x^(2)(3x^(2)-4))/((3x^(2)-4)(3x+2))`
`=underset(xtooo)lim(2x^(3)+4x^(2))/(9x^(3)+6x^(2)-12x-8)`
`=underset(xtooo)lim(2+(4)/(x))/(9+(6)/(x)-(12)/(x^(2))-(8)/(x^(3)))`
`=2//9`
