Question

A quadratic polynomial whose zeroes are and is

Answer 1

Answer:

x^2 +9+20

Step-by-step explanation:

let the zero of the quadratic polynomial be ;

Then ,

So,

sum of 0 = -9

product of 0 = 20

then ,

the quadratic polynomial ;

=> x^2 - (sum of zeros) + product of zeros

=> x^2 -(-9)+20

=>x^2 +9+20

a quadratic polynomial whose zeroes are - 4 and -5 is x^2 +9+20 .

Hope it helps you.
