Tentukan nilai limit dg memakai cara pemfaktoran : 1. lim X→1 X^3 - 1 / X-1 = 2. lim X→3 X^3 - 27 / 2x²-6x = Pakai cara yang pemfaktoran ya... Please tolong

1. lim x³-1/x-1
x->1
lim (x²+x+1)(x-1)/(x-1)
x->1
= 1²+1+1
=3

2. lim x³-27/2x²-6x
x->3
lim (x²+3x+9)(x-3)/2x(x-3)
x->3
lim (x²+3x+9)/2x
x->3
=(3²+3(3)+9)/2(3)
=(9+9+9)/6
=27/6
