Answer 2

$\large\bf{\underline\orange{Answer \: :- }}$

Que :- Find the quadratic polynomial whose zeroes are 4+√5 and 4-√5.

Ans :- Sum of zeroes = 4+√5 + 4-√5.

= 8

Product of zeroes = (4+√5)(4-√5)

= (4)² - (√5)²

= 16 - 5

= 11

Now

Sum of zeroes = -b/a

= -8/1

Product of zeroes = c/a

= 11/1

a = 1

b = -8

c = 11

Putting it in quadratic equation ax² + bx + c = 0

x² - 8x + 11 = 0
