Lesson Summary:
In this video, Julie Harland teaches how to divide a polynomial by a linear binomial using synthetic division. She shows how to use the method when the coefficient of x in the linear binomial is not 1. Julie emphasizes the importance of writing the polynomial in descending order and dividing the coefficients of the quotient by the coefficient of x in the linear binomial. She concludes by demonstrating how to check the answer.
