Question

form a Polynomial whose zeroes are 1 , -2 & 3 ​

Answer 1

here,

$\alpha + \beta + \gamma \\ = 2$

and

$\alpha \beta + \beta \gamma + \gamma \alpha \\ = - 8 + 3 \\ = - 5$

and

$\alpha \beta \gamma \\ = - 2 \times 3 \\ = - 6$

so,polynomial is

${x}^{3} - 2 {x}^{2} - 5x + 6$

Here is your answer
