The video tutorial explains how to use the binomial theorem to expand the expression (2x - 3)^4. It begins with an introduction to the theorem, followed by a detailed explanation of the pattern in the theorem, including combinations and factors of x and y. The tutorial then applies the theorem to expand the given expression, showing each step in detail. Finally, it simplifies the expanded terms and concludes with a complete expansion. The video also mentions using Pascal's triangle for finding combinations, which will be covered in another video.

What is the primary purpose of using the binomial theorem in this context?

• To expand expressions raised to a power

• To simplify linear equations

• To calculate derivatives

• To solve quadratic equations
