. Which of the following is a zero of the polynomial f(x)= x5+2x4+x+2?
A. I
B.-1
C.-2
D. 2​

Answer 1

x = -2 is a function

Explanation:

To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1

we have this as:

Let us try the value x = -2

-2^5 + 2(-2)^4 - 2 + 2

= -32 + 32 - 2 + 2 = 0

This means that the term x = -2 is a root of the equation
