Polynomial Division and Remainder Theorem

The video tutorial explains how to solve a polynomial remainder problem. It begins with an introduction to the problem, followed by setting up the polynomial expression and remainder. The remainder theorem is applied to interpret the given data, leading to the derivation and solving of simultaneous equations for unknowns A and B. Finally, the remainder of the polynomial is calculated, providing a complete solution to the problem.
