The video tutorial explains the remainder theorem, emphasizing its connection to synthetic division. It begins by reviewing a previous example where a polynomial is divided by X-3, resulting in a remainder of 19, which is verified using the theorem. The tutorial then explores a new example with X-5, demonstrating the calculation and verification process, resulting in a remainder of 193. The video aims to solidify understanding of the remainder theorem through practical examples.
