Question

find remainder using remainder therom

Answer 1

Answer:

Step-by-step explanation:

X^3 +1

Put x= - 1

= (- 1)^3 +1

= - 1 +1

=0

Hence it is a root of the polynomial

Answer 2

p(x)= (x3+1)

g(x)= (x+1)

now,g(x)= x+1

x+1= 0

x= (-1)

now, p(x) becomes,

= (-1×-1×-1 +1)

= 0

So, the remainder is 0
