We notice that substituting x by 2, we'll get a
indetermination case:
lim (x^3-2x^2)/(x-2) = (8 - 8)/(2-2)
= 0/0
We'll factorize the numerator by
x^2:
lim (x^3-2x^2)/(x-2) = lim x^2(x -
2)/(x-2)
We'll simplify and we'll
get:
lim x^2(x - 2)/(x-2) = lim
x^2
We'll substitute x by
2:
lim x^2 =
2^2
lim (x^3-2x^2)/(x-2) =
4
