Long Division and Synthetic Division Practice

What does it mean if the remainder is zero after performing synthetic division?

• The divisor is not a factor of the polynomial.

• The polynomial is not divisible by the divisor.

• The divisor is a factor of the polynomial.

• The polynomial has no roots.

Why can't synthetic division be used when the denominator is x squared?

• Because synthetic division is only for cubic polynomials.

• Because the numerator must be a higher degree.

• Because x squared is not a polynomial.

• Because synthetic division only works with linear factors.
