Understanding the Remainder Theorem and Factors

The video tutorial explains the remainder theorem and its application in determining if a binomial is a factor of a polynomial. It covers the importance of zeros in graphing, demonstrates synthetic division with examples, and discusses the implications of non-zero remainders.

What is the significance of finding zeros in a polynomial function?

• They represent the points where the graph crosses the x-axis.

• They are the points where the graph is undefined.

• They indicate where the graph crosses the y-axis.

• They show the maximum points of the graph.

In the context of the Remainder Theorem, what does it mean if a binomial is a factor of a polynomial?

• The polynomial is undefined.

• The polynomial has no zeros.

• The remainder is zero.

• The remainder is non-zero.

What is the first step in using synthetic division to determine if a binomial is a factor?

• Multiply all coefficients by zero.

• Graph the polynomial.

• Add a placeholder for missing terms.

• Divide the polynomial by the binomial.

When using synthetic division, what does a remainder of zero indicate?

• The binomial is not a factor.

• The polynomial is undefined.

• The binomial is a factor.

• The polynomial has no zeros.

In the example with p to the power of four, what was the result of the synthetic division?

• The polynomial had no factors.

• The remainder was zero.

• The remainder was non-zero.

• The polynomial was undefined.

What does a non-zero remainder in synthetic division imply about the binomial?

• The binomial is not a factor.

• The polynomial has no zeros.

• The binomial is a factor.

• The polynomial is undefined.

If a polynomial has a zero remainder when divided by a binomial, what can be concluded?

• The polynomial has no zeros.

• The binomial is not a factor.

• The polynomial is undefined.

• The binomial is a factor.

What is the purpose of using synthetic division in polynomial factorization?

• To find the y-intercept.

• To determine if a binomial is a factor.

• To graph the polynomial.

• To find the maximum points of the graph.

What happens if the remainder is not zero in synthetic division?

• The polynomial is undefined.

• The binomial is a factor.

• The polynomial has no zeros.

• The binomial is not a factor.

Why is it important to ensure there are no gaps in the polynomial when using synthetic division?

• To avoid incorrect calculations.

• To find the y-intercept.

• To ensure the graph is accurate.

• To make the polynomial undefined.
