Squaring Binomials and Expansions

The video tutorial covers the concept of special products, focusing on binomials raised to the second power. It provides examples of solving expressions like N2 + r2 and W + 3H using the distributive property. The tutorial also introduces a formula for quickly solving these types of problems, emphasizing the efficiency of using formulas over term-by-term distribution.

What is the result of squaring a binomial?

• Adding the binomial to itself

• Multiplying the binomial by a different binomial

• Multiplying the binomial by itself

• Subtracting the binomial from itself
