Question

a quadratic polynomial whose zeroes are 5 and -8 is​

Answer 1

Step-by-step explanation:

You'r answer is given in the above picture hope u understand

Answer 2

Step-by-step explanation:

let alpha=5 and beta= -8

sum of zeroes = 5 - 8= -3

product of zeroes = 5 x -8= -40

hence the quadratic polynomial is

Kx square + sum of zeroes multiply x + product of zeroes

putting the values in quadratic polynomial

= kx square - 3 + -40

=. -43

Kx square - 43 where k is constant.
