Answer 2

Answer:

The sum of zeros is 0.

Step-by-step explanation:

Given : The polynomial $5x^2-7$

To find : The sum of zeros of the polynomial?

Solution :    

General form - $ax^2+bx+c=0$

On comparing with the given polynomial $5x^2-7$,

a=5 , b=0, c=-7

If α and β are the roots of the equation then

The sum of zeros,

$\alpha + \beta =-\frac{\text{coefficient of } x}{\text{coefficient of } x^2}$

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

$\alpha + \beta =-\frac{0}{5}$

$\alpha + \beta =0$

The sum of zeros is 0.
