Mastering Polynomial Operations: Addition, Subtraction, and Multiplication

The video tutorial introduces polynomials and explains how to combine them through addition, subtraction, and multiplication. It covers the process of adding and subtracting polynomials by aligning like terms and demonstrates the FOIL method for multiplying polynomials. The tutorial also emphasizes the importance of the distributive property in polynomial multiplication.

What is the first step in adding two polynomials?

• Combine all terms together

• Multiply the coefficients

• Subtract the constants

• Align like terms
