What does a remainder of zero in synthetic division indicate?

• The divisor is not a factor

• The polynomial has no real zeros

• The divisor is a factor

• The polynomial is irreducible

What is the significance of a zero with multiplicity in a polynomial?

• It means the polynomial is linear

• It shows a complex root

• It indicates a repeated root

• It suggests an error in calculation

How can you express a polynomial in terms of its linear factors?

• By using the quadratic formula
