Learn how to subtract two polynomials using two different methods

The video tutorial explains how to subtract trinomials by aligning them in descending order and converting the subtraction into an addition problem. The instructor demonstrates the process of distributing the negative sign and changing the signs of terms to simplify the problem. The tutorial emphasizes the ease of addition over subtraction and provides a detailed walkthrough of solving the problem, highlighting common mistakes and tips for accuracy.

What is the first step recommended when subtracting trinomials?
