Question

Given that one of the zeroes of the cubic polynomial ax^3+bx^2+cx+d is zero, the value of c is
a) less than 0
b) greater than 0
c) equal to 0
d) can't say

Answer with step-by-step Explanation​

Answer 1

Answer:

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
