Nilai lim x-> takterhingga 2x² - 5x/ 3-√9+x adalah...?

limit tak hingga

lim(x->∞)  (2x² -5x) / { 3 - √(9+x)}
kalikan akar sekawan
lim(x->∞)  [(2x² - 5)(3 +√(9+x)]/ [(3-√(9+x))(3+√(9+x)}
lim(x->∞) [(2x²-5)(3+√(9+x)] / [(9- 9 - x)]
lim(x->∞) [ (2x²-5)(3+√(9+x)] / [ -x ]
= (2 -0)(0+0)/(-0)
= -(2)/(0)
=- ∞
