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.
