Question

when a ploynomial (x^3+1) is divided by (x+1) find the remainder ​

Answer 1

Answer:

${ \div < | | |. = | | | }^{?}$

Answer 2

Answer:

Here's the correct answer

Step-by-step explanation:

Given, polynomial x

3

+1 divided by (x+1).

Then, f(x)=x

3

+1.

The polynomial is divided by (x+1) .

Then put (x+1)=0⟹ x=−1, we get,

f(−1)=(−1)

3

+1

⇒f(−1)=−1+1

⇒f(−1)=0.

So, when f(x)=x

3

+1 is divided by x+1, the remainder obtained is zero.

So, by Remainder Theorem, we know that f(x)=x

3

+1 when divided by x+1, gives 0 as the remainder.

Here's the correct answer..
