Lesson Summary:

In this lesson, the instructor shows how to divide a polynomial with four terms by a binomial using long division. The steps involve concentrating on the first term out in front and the first term inside, multiplying them, and subtracting the result from the dividend. The process is repeated until a remainder is obtained, and the answer is written as a quotient plus the remainder over the divisor. The lesson also emphasizes that the polynomial terms must be arranged in descending order for the method to work.

Lesson Description:

This is Part 2 of Dividing Polynomials using long division. The example shows how to divide a polynomial with 4 terms by a binomial. See Part 3 for how to check the answer to this problem.

    This lesson shows a bit more difficult of a polynomial long division example. This time, there is a remainder. Each step is shown clearly again in this example.
