Lim x²-1 / x² + 2x + 1 x-->2

Langsung aja y

lim x→2 (x²-1) / (x²+2x+1)

lim x→2 (x-1)(x+1) / (x+1)(x+1)

lim x→2 (x-1) / (x+1)

= (2 - 1) / (2 + 1)
= ⅓

Semoga berguna +_+

Lim       (x² - 1)/(x² + 2x + 1)
x --> 2

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