`lim_(xto1) ((2x-3)(sqrtx-1))/(3x^(2)+3x-6)` का मान गये कीजिये।

Answer» `underset(x to 1)lim((2x-3)(sqrtx-1))/(3x^(2)+3x-6)=underset(xto1)lim((2x-3)(sqrtx-1)(sqrtx+1))/(3(x^(2)+x-2)(sqrtx+1))`
`=underset(xto1)lim((2x-3))/(3(x+2)(x-1))((x-1)/(sqrtx+1))`
`=underset(xto1)lim ((2x-3))/(3(x+2)(sqrtx+1))=(-1)/(18)`
