Solution

We can find the quadratic polynomial if we know the sum of the roots and product of the roots by using the formula
`x^2` – (sum of the zeroes)x + product of zeroes  

We can find the quadratic polynomial if we know the sum of the roots and product of the roots by using the formula 

`x^2 `– (sum of the zeroes)x + product of zeroes 

`⇒ x^2-(-1/2)x+(-3)` 

`⇒x^2+1/2x-3` 

Hence, the required polynomial is `x^2+1/2x-3`
