Let p(x) =  {x}^{2} - 3

Zero of the polynomial is the value of x where,

p(x) = 0

Putting p(x) = 0

 {x}^{2} - 3 = 0

 {x}^{2} - {\sqrt{3}}^{2} = 0

Using:-

 {a}^{2}  -  {b}^{2}  = (a  -  b)(a  +  b)

(x -  \sqrt{3} )(x +  \sqrt{3} ) = 0

So,

x =  \sqrt{3}  \:  and \:  \sqrt{ - 3}

Therefore,

 \alpha  =  \sqrt{3}  \: and \:  \beta  =  \sqrt{ - 3}

are the zeros of the polynomial.

We can write,

p(x) =  {x}^{2}  - 3

 =  {x}^{2}  + 0 - 3

 =  {1x}^{2}  + 0x - 3

This equation is form of  {ax}^{2} + bx + c

So,

a = 1, \: b = 0, \: c = 3
