Question

Given that two of the zeroes of the cubic polynomial ax³ + bx² + cx + d are 0, the third zero is​

Answer 1

Answer:

the third zero is minus d

Answer 2

Step-by-step explanation:

Given two zeroes of a cubic polynomial

(ax³ + bx² +cx + d) are zero.

Let third zero be y

then sum of zeroes = (−b/a)

⇒0+0+y = (–b/a)

⇒y = (−b/a)

So the answer is (–b/a)
