Question

Lim x^4 - 4x + 3/per
x→1 x^3 - 3x + 2 =

Answer 1

X^4-4x+3 / x^3-3x+2

=
4x^3-4 / 3x^3-3
=
4x-4 / -3
=
-3 / -3
=
1

saya masih ragu ragu tapi, :p

Answer 2

Limit  (x^4 - 4x+3)/
x->1 (x^3 -3x+2)

lim (x-1)²(x²+2x+3) per
x->1 (x-1)²(x+2)                              coret (x-1)²

sehingga
lim (x²+2x+3) per
x->1 (x+2)

(1² + 2(1) + 3) per (1+2) = 6/3 = 2
