Question

Find a quadratic polynomial whose one of the zeroes is -15 and sum of the zeroes is 42.

Answer 1

Hi friend !!

======================

let other zero be x

x-15= 42
x = 42+15
x = 57

the product of zeroes is 57×-15 = -855

the quadratic polynomial

x²-(sum of zeroes)x+product of zeroes

= x²-42x+-855

= x²- 42x - 855

Answer 2

HELLO.......FRIEND!!

THE ANSWER IS HERE,

One of the zero => -15.

Let the other zero be x.

So, From the question,

=> x-15 = 42

=> x=42+15

=> 57.

Product of zeroes=> 57 ×(-15)

=> -855

Quadratic equation,

$= > \: {x}^{2} - (sum \: of \: zeroes)x + product \: of \: zeroes$

$= > \: {x}^{2} - 42x - 855$

:-)Hope it helps u.
