Question

1. Write a quadratic polynomial whose zeroes are 2 and -1​

Answer 1

Answer:

x^2 - x -2

Step-by-step explanation:

polynomial based on its zeroes as a,b = (x-a)(x-b)

so here a= 2 , b= -1

polynomial = (x-2) * (x-(-1))

=(x-2) * (x+1)

= x*x -2x +x -2

= x^2 -2x -2

( it's X square minus two X minus 2, mentioning this as I can't write here in the way we write on paper)

Answer 2

answer: x^2+ x-6

hope it helps you!
