Question

is n=3 is zero of of the polynomial n3-3n2+n-3​

Answer 1

Step-by-step explanation:

=>n3-3n2+n-3

n=3

Therefore

=>(3)3-3*(3)2+3-3

=>9-18+3-3

=> -9

To check whether a number is zero of a polynomial or not:

• Put that number in the polynomial in place of the variable.
• If the polynomial becomes zero, it is a zero of the polynomial.
• If it doesn't become, it is not a zero of that polynomial.

Here,

Put n = 3 in n^3 - 3n^2 + n -3

=> (3)^3 - (3)(3)^2 + 3 - 3

=> 27 - 27 + 3 - 3

=> 0

Thus n=3 is a zero of the polynomial n^3 - 3n^2 + n - 3.
