Question

1. Check whether 2 is the zero of the cubic polynomial.
x3 - 3x2 + 3x - 2​

Answer 1

Answer:

yes, it is

Step-by-step explanation:

if 2 is a zero, then putting 2 in place of x should give 0.

=> 8 - 3*4 + 3*2 -2

=>0

So 2 is a zero

Answer 2

Answer:

Just put 2 in the polynomial

Step-by-step explanation:

p(2) = 0

2^3 - 3*2^2+3*2-2 = 0

8-12 + 6 -2 =0

-4+4=0

0=0

Hence 2 is a zero of the cubic poly.
