Question

3.Find the remainder obtained on dividing p(x) = x3 + 1 by x + 1​

Answer 1

Answer:

0

Step-by-step explanation:

The zero of x+1 is -1

Therefore remainder = p(-1)

= (-1)^3+1 = -1+1 =0

Answer 2

Given p(x)=x3+1 

x+1x3+1=x+1(x+1)(x2−x+1)=x2−x+1

Therefore, p(x) is divisible by x+1.

Hence, the remainder is zero.
