Hasil dari lim x mendekati 3 dari x-3/2-(akar x +1)

Limit

lim (x -> 3) (x – 3) / (2 - √(x + 1))

lim (x -> 3) (x – 3) (2 + √(x +1)) / (2 - √(x+1)) (2 + √(x +1))
lim (x -> 3) (x – 3)(2 + √(x +1)) / (4 – (x + 1))
lim (x ->3)  (x – 3)(2 + √(x +1)) /(4 – x – 1)
lim (x-> 3) (x – 3)(2 + √(x+1)) / ( 3- x)
lim (x -> 3) (x – 3)(2 + √(x +1)) / – (x – 3)
lim (x -> 3)  – (2 + √(x +1))
x= 3
limit = -  (2 + √(3+1)) = – (2 + √4) = – (2 +2)
limit = – 4
