Question

What is correct answer?​

Answer 1

D) All of the above.

Explanation:

A "zero" is a root of a polynomial. For a polynomial root to be real, however, it must also intersect the x-axis. Furthermore, a real root is defined to be one that is non-imaginary. The answer is thus D) all of the above.

Answer 2

I would say all of the above

Explanation:

A real zero of a polynomial is a real number that results in a value of zero when plugged into the polynomial. Algebraically, these can be found by setting the polynomial equal to zero and solving for x (typically by factoring).

The real zeros of a polynomial are found when setting a polynomial P ( X ) = 0 . The real zeros will come from factoring the polynomial and setting it equal to zero. This cannot include imaginary solutions.

If we modify the same definition to something like: imaginary numbers are the numbers who lie solely on the y-axis and real number are the numbers who lie solely on the x-axis, '0' lies on both, the y-axis and the x-axis.
