Question

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

Answer 1

Answer:

Let α,0,0 be the zeros of ax3+bx2+cx+d. Then, sum of zeros = -ba⇒α+0+0=-ba⇒α=-ba. Hence, the third zeros is -ba.

Step-by-step explanation:

Given two zeroes of a cubic polynomial=

ax3+bx 2+cx+d

are zero, Let third zero be y

then sum of zeroes = −b/a

⇒0+0+y= -b/a

⇒y= -b/a.
