उत्तर

We know the sum, sum of the product of the zeroes taken two at a time and the product of the zeroes of a cubic polynomial then the cubic polynomial can be found as `x^3` – (sum of the zeroes)`x^2` + (sum of the product of the zeroes taking two at a time)x – product of zeroes Therefore, the required polynomial is 

`x^3 – 5x^2 – 2x + 24`
