  2. Answer:

    Given :-

    α+β=

    2

    5

    αβ=1

    P(x)=x

    2

    −(α+β)x+αβ

    P(x)=x

    2

    −

    2

    5

    x+1

    =2x

    2

    −5x+2

    P(x)=0

    2x

    2

    −5x+2=0

    2x

    2

    −4x−x+2=0

    2x(x−2)−1(x−2)=0

    (2x−1)(x−2)=0

    2x−1=0 & x−2=0

    x=

    2

    1

    & x=2 are zeros of P(x)
