Question

find a cubic polynomial whose zeroes are 2,3and4

Answer 1

Answer:

Answer

If the zeroes of the cubic polynomial are a, b and c then the cubic polynomial can be found as.

x3 – (a + b + c)x2 + (ab + bc + ca)x – abc ……( ...

Let a = 2, b = –3 and c = 4.

Substituting the values in 1, we get.

x3 – (2 – 3 + 4)x2 + (– 6 – 12 + 8)x – (–24)

⇒ x3 – 3x2 – 10x + 24.

Answer 2

Answer:

If the zeroes of the cubic polynomial are a, b and c then the cubic polynomial can be found as  x3 – (a + b + c)x2 + (ab + bc + ca)x – ab

.(1)  Let a = 2, b = –3 and c = 4  Substituting the values in 1, we get  x3 – (2 – 3 + 4)x2 + (– 6 – 12 + 8)x – (–24)  ⇒ x3 – 3x2 – 10x + 24Read more on Sarthaks.com - https://www.sarthaks.com/128619/find-a-cubic-polynomial-whose-zeroes-are-2-3-and-4.
