Question

if all the three zeroes of a cubic polynomial are equal to 2 then the polynomial is​

Answer 1

Step-by-step explanation:

let alpha= 2

beta= 2

gama= 2

alpha,beta, gama are the zeros of cubic polynomial

then, the required polynomial

= x³- (alpha+beta+gama)x²

+(al×be+ be×ga+ga×al)x - al×be×ga

= x³- (2+2+2) x²+(2×2+2×2+2×2)x - (2×2×2)

=x³- 6x²+12x-8
