p(x) = x² -2x + 5
α and β are zeros of p(x)
α + β = -b/a = 2
αβ = 5
--------------------------------------------
Zeros of other polynomial :-
α + β = 2
1/α + 1/β = α + β /αβ
= 2/5
here ,
2 and 2/5 are zeros of a polynomial
sum of zeros = 2 + 2/5 = 10/5 + 2/5 = 12/5
product of zeros = 2×2 /5 = 4/5
a quadratic polynomial is given by:-
k [ x² - (sum of zeros )x + (product of zeros) ]
k [ x² -12/5x + 4/5 ]
5[x² - 12/5x + 4/5]
5x² -12x + 4 -----> required polynomial
