Question

Find the zeros of the dollowing quadratic polynomial and verify the relationship between the zeroes and coefficient :-

a) X² - 2
b) X² - 9​

Answer 1

Step-by-step explanation:

a),X2-2 or (X2-underoot 2)^2

(X-underoot2)(X+root2) {using identity (a-b)(a+b)}

the zeroes are X=root 2 and X = - root 2

verification-:

sum of zeroes= -(coefficient of x/coefficientof x2)

Root2-root2= -(0/1)

0=0

product if zeroes= constant term/coefficient of X2

root2×root2=2/1

2=2

B) zeroes are x=3 and x=-3

verification will be the same which is given above only the values will change
