Answer 1

Answer:

firstly we have to find zeroes of the polynomial

Step-by-step explanation:

x2+1x+1x+1=0

x(×+1)+1(x+1)

(x+1)(x+1)

×= -1, -1

sum of zeroes=-1-1= -2

Answer 2

Answer:

( - 1)

Step-by-step explanation:

Given quadratic equation has only one zero

x² + 2x + 1 = (x + 1)²

If (x + 1)² = 0 , then x = - 1

Thus, sum of zeros is ( - 1 )
