If one of the zer A. – c/a

B. c/a

C. 0

D. – b/a

Answer :

let α, β & γ be the zeroes of the polynomial ax3 + bx2 + cx + d

And let α = 0(given)


sum of the product of two zeroes at a time = coefficient of x ÷ coefficient of x3 i.e.


c/a = sum of the product of two zeroes at a time


c/a = αβ + βγ + γα


c/a = β (0) + βγ + γ (0) (putting α = 0)


c/a = βγ


The product of the other two zeroes is c/a
