The video tutorial explains how to subtract polynomials by converting the subtraction into an addition problem. It emphasizes the use of the distributive property to handle negative signs and demonstrates how to combine like terms to arrive at the final result. The process involves rewriting subtraction as addition, applying the distributive property, and carefully combining terms with the same variable and power.
