Question

Form a quadratic polynomial, whose one of the zeroes is (2+ V5) and the sum of
the zeroes is 4.​

Answer 1

Explanation:

one of the zero is 2+√5and the sum of zeroes is 4

therefore,sum of zeroes=sum of the zeroes

therefore,4=2+√5+x

x=2-√5

therefore the anther zero is 2-√5

now the required polynomial is x^2-(sum of zeroes)+(product of zeroes)

therefore the polynomial is

x^2-4+(-1)

therefore the polynomial is

x^2-5
