Question

a
1. If a, ß are the zeros of the polynomial f(x) = x2 + x + 1, then
(a) 1
(b) -1
(c) 0
(d) None of these​

Answer 1

none of these

Step-by-step explanation:

a simple technique is to substitute the values of x in the equation

a) 1²+1+1=1+1+1=3

b) -1²-1+1=1-1+1=1

c) 0²+0+1=0+0+1=1

d) none

so by the proof you can see that "d" is the answer

hope it helps you please mark me as brainliest

Answer 2

Answer:

$\alpha +\beta =-\frac{b}{a} =\frac{-1}{1} =-1\\\alpha \beta =\frac{c}{a} =\frac{1}{1} =1$

Step-by-step explanation:

so$\alpha +\beta =-1\\\alpha \beta =1$
