What does a remainder of zero indicate in synthetic division?

• The polynomial is irreducible

• The divisor is a factor of the polynomial

• The divisor is not a factor of the polynomial

• The polynomial has no real roots

Which method can be used to verify if a number is a zero of a polynomial?

• Both synthetic division and remainder theorem

How many zeros should a polynomial of degree 3 have?

• Two

• One

• Three

• Four

What is the result of dividing a polynomial by one of its factors?

• A remainder equal to the leading coefficient

• A remainder equal to the constant term

• A remainder of zero

• A remainder equal to the degree of the polynomial

What is the purpose of using synthetic division in this context?
