Find the Polynomial

Answer

According to question

Given that

-2 and 5

$\bf \red{let \: be \: \alpha = - 2} \\ \\ \bf \red{and} \\ \\ \bf \red{ \beta = 5} \\ \\ \bf \red{using \: this \: formula } \\ \\ \bf \red{(x - \alpha )(x - \beta )} \\ \\ \bf \red{(x + 2)(x - 5)} \\ \\ \bf \red{ {x}^{2} - 5x + 2x - 10 } \\ \\ \bf \red{ {x}^{2} - 3x - 10 \: \: \: answer }$

Answer 2

Zeroes : - 2 and 5

Sum of zeroes : - 2+5=3

Product of zeroes : - 2 x 5= - 10

By using formula ( x2 - (sum of zeroes)x + product of zeroes)

We get ,

x2 - 3x + (-10)

x2 - 3x - 10
