Examples, solutions, videos, and lessons to help High School students know and apply the Remainder Theorem and Factor Theorem:
For a polynomial p(x) and a number a, the remainder on division by x – a is p(a),
so p(a) = 0 if and only if (x – a) is a factor ofp(x).

Suggested Learning Targets

  • Understand and apply the Remainder Theorem.
  • Understand the Factor Theorem, that a is a root of a polynomial function if and only if x-a is a factor of the function.
