A polynomial P(x), whose degree is greater than 3, when divided with (x - 1) leaves a remainder 0. when divided by (x - 1)³ leaves a remainder x -1. Find the remainder when P(x) is divided by (x - 1)²

Step-by-step explanation:
Given P(1)=3
P(3)=5
Let r(x)=ax+b
So P(x)=(x−1)(x−3)q(x)+ax+b
P(1)=a+b⇒ a+b=3
P(3)=3a+b⇒ 3a+b=5
a=1,b=2
r(x)=ax+b=x+2
r(−2)=(−2)+2)
r(−2)=0
