Question

check whether x=root(3) is a zero of the polynomial x^3-3*root(3)

Answer 1

Yes it's a zero of the given equation...we can check it by putting the value in the equation..
x^3 - 3✓3 = 0
now put x = ✓3
✓3^3 - 3✓3 =0
3✓3 - 3✓3 = 0
0 = 0

Answer 2

hey buddy,
let's check it out,
according to question,
x = √3
then,
putting the value,
(√3)^3 -3*√3
= 3×√3 - 3× √3
=0
hence it is a zero of the polynomial.

hope it will help
