• The remainder.

• The coefficients.

• The divisor.

How do you determine if a polynomial is a factor of another polynomial using synthetic division?

• Check if the quotient is zero.

• Check if the remainder is zero.

• Check if the divisor is zero.

• Check if the dividend is zero.

What is the purpose of factoring by grouping?

• To solve quadratic equations.
