Question

Form a quadratic polynomial whose one of the zeros is minus 15 and sum of the zeros is 42

Answer 1

Let the another zeros be x
and the given zeros -15

Given,
Sum of zeros=42

x+(-15)=42

x=42+15

x=57

Now to form we should now product of zeros,
So,

product of zeros
=57×(-15)

=-855

⭐To form equation we have following formula:-

$x ^{2} - (sum \: of \: zeros)x + (product \: of \: zeros)$

The required quadratic equation is:-

x²-42x-855
