The Remainder Theorem

Videos and lessons to help High School students know and apply the Remainder 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 that a is a root of a polynomial function if and only if x-a is a factor of the function.
