The video tutorial provides an overview of dividing polynomials, focusing on long division and synthetic division methods. It emphasizes the importance of placeholders in polynomial division and explains how to find factors and zeros. The tutorial also covers evaluating zeros and their significance in graphing polynomials.

Why is it important to include a placeholder for missing degrees in polynomial long division?

• To make the polynomial look longer

• To ensure every degree is accounted for

• To make the division process faster

• To confuse the solver

What is the first step in the long division method for polynomials?

• Dividing the highest degree term of the dividend by the highest degree term of the divisor

• Adding the divisor to the dividend

• Multiplying the divisor by the highest degree term of the dividend

• Subtracting the divisor from the dividend
