How do you determine if (x - c) is a factor of a polynomial?

Back

Use the Factor Theorem: If f(c) = 0, then (x - c) is a factor of the polynomial f(x).

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

How do you find the quotient in polynomial division?

Back

To find the quotient, divide the leading term of the dividend by the leading term of the divisor, then multiply the entire divisor by this result and subtract from the dividend.

How do you set up synthetic division?

Back

To set up synthetic division, write the coefficients of the polynomial in descending order and use the zero of the divisor (x - c) as the value for synthetic division.
