Question

Write the cubic polynomials with zeroes -2,1,4

Answer 1

Step-by-step explanation:

we have the zeroes -2,1,4

for a cubic polynomial

k[x^3-(sum of zeroes)x^2+(sum of product of zeroes)x-product of zeroes]

where k is non zero real no.

x^3-(-2+1+4)x^2+(-2×1+1×4+4×(-2))x-(-2×1×4)

x^3-3x^2-6x+8

it is required cubic polynomial
