lim x mendekati 3 x kuadrat-2x+1/x-1

lim (x²-2x+1) / (x-1)
= lim (x-1)(x-1) / (x-1)
= lim (x-1)

subtitusikan 3 ke x
= 3-1
= 2

Lim      (x² - 2x + 1)/(x - 1)
x → 3

Jwb:
(x² - 2x + 1)/(x - 1)
= (x - 1)(x - 1)/(x - 1) ------->> (coret "x - 1")
= x - 1 ---------->> (masukkan nilai "x → 3")
= 3 - 1
= 2
