11) Which of the following is zero of the polynomial x^3+x^2+x+1
Mrac [35]

Answer:

<em>Answer: -1</em>

Step-by-step explanation:

<u>The Polynomial Remainder Theorem</u>

It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial:

f(x)=x^3+x^2+x+1

And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.

Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.

Find:

f(1)=1^3+1^2+1+1

f(1)=4

Thus, x=1 is not a zero of f(x)

Now, find:

f(-1)=(-1)^3+(-1)^2+(-1)+1

f(1)=-1+1-1+1=0

Thus, x=-1 is a zero of f(x)

Answer: -1
