Question

. Given that two of the zeroes of the cubic polynomial ax + bx² + cx +d are 0,the value of c is
a) less than 0
b) greater than 0
C) equal to 0
d) can't say.​

Answer 1

Answer:

Given two zeroes of a cubic polynomial ax

3

+bx

2

+cx+d

are zero, Let third zero be y

then sum of zeroes =

a

−b

⇒0+0+y=

a

−b

⇒y=

a

−b
