Question

given that one of the zeros of cubic polynomial is x cube + 3 X square + 3 X + B then find the sum of reciprocal of other two zeros​

Answer 1

Correct option is

B

a

c

For the given equation, ax

3

+bx

2

+cx+d, 0 is the root of this equation implies d=0

Hence, the equation is x(ax

2

+bx+c)

The other two roots will be from ax

2

+bx+c

Product of the other roots =

a

c
