What is a root of a polynomial?

Back

A root of a polynomial is a value of x that makes the polynomial equal to zero.

Front

What is the relationship between the degree of a polynomial and the number of roots?

Back

The degree of a polynomial indicates the maximum number of roots it can have, including real and complex roots.

Front

What are complex roots?

Back

Complex roots are roots of a polynomial that have a real part and an imaginary part, typically expressed in the form a + bi.

Front

What is the significance of complex conjugate roots in polynomials?

Back

If a polynomial has real coefficients, then any complex roots must occur in conjugate pairs (e.g., a + bi and a - bi).

How do you determine the number of real roots of a polynomial?

Back

The number of real roots can be determined using the polynomial's degree and the nature of its coefficients, often analyzed through the discriminant.
