Question

1. Define zero or root of a polynomial.​

Answer 1

Step-by-step explanation:

A root or a zero of a polynomial are the value(s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0.
