Question

A polynomial equation has roots at x=+-l and x=2i. What is the minimum degree of the polynomial quation?

Answer 1

The minimum degree of the polynomial equation is 4.

Step-by-step explanation:

The minimum degree of a polynomial equation is determined by the number of roots it has. In this case, the given polynomial equation has two real roots at x = ±1 and two imaginary roots at x = ±2i. Since imaginary roots always come in conjugate pairs, the polynomial equation must have a minimum degree of 4. Therefore, the minimum degree of the polynomial equation is 4.
