Zeros of Polynomials
Videos and lessons to help High School students identify zeros of polynomials when suitable factorizations
are available, and use the zeros to construct a rough graph of the function defined by the polynomial.
Suggested Learning Targets
- Find the zeros of a polynomial when the polynomial is factored.
- Use the zeros of a function to sketch a graph of the function.
