Sum of zeros in polynomial x2+4x+7 is

-4

Step-by-step explanation:

Hello,

let say that and are two zeros of second order polynomial

it can be then be written

So when we check this expression

we can say that the sum of zeros is -4

and the the product of zeros is 7

to note that in this example there are no real root of this equation

here, the zeros are complex numbers not real ones

if I have to solve it in I would say that there are no zeros so their sum is not defined

if I have to solve it in I would say that there are two complex roots and their sum is -4

hope this helps
