P (x) = (x+1) =3
x + 1 = 0
x = -1
P ( -1 ) = 3

P ( x ) = ( x - 1 ) = 5
x - 1 = 0
x = 1
p ( 1 ) = 5

P(x) = ( x2 - 1 ) = ( x + 1 ) ( x -1 ) = ax + b
p ( -1 ) = -a + b = 3
p ( 1 ) = a + b = 5 -
                 -2a = -2
                   a = 1
a + b = 5
1 + b = 5
b = 5 - 1
b = 4

sisa ( x2 - 1 ) = ax + b
                    = x + 4
