Complex zeros are values of x when y equals zero, but they can’t be seen on the graph. Complex zeros consist of imaginary numbers. An imaginary number, i, is equal to the square root of negative one.

Can zeros of a polynomial be imaginary?

For example, the polynomial function P(x) = 4ix2 + 3x – 2 has at least one complex zero. … For example, P(x) = x5 + x3 – 1 is a 5th degree polynomial function, so P(x) has exactly 5 complex zeros. P(x) = 3ix2 + 4x – i + 7 is a 2nd degree polynomial function, so P(x) has exactly 2 complex zeros.

Can a polynomial have imaginary coefficients?

Polynomials can also have complex coefficients.
