Dividing Polynomials with Synthetic Division

Mr. Anderson introduces synthetic division as a simpler alternative to long division for polynomials. He provides three examples: a basic example, one with missing terms, and a complex example involving fractions. The video emphasizes the step-by-step process and highlights the importance of handling coefficients and remainders correctly.

What is synthetic division primarily used for?

• Solving quadratic equations

• Dividing polynomials

• Finding the greatest common divisor

• Calculating derivatives
