Step by Step Written Solution
Hi Selen, let's solve this algebraic expansion together.
Algebraic Expansion
We are given the product of two binomials: x minus y and x plus y.
To solve this, we will use the distributive property, often called the FOIL method, where we multiply every term in the first parenthesis by every term in the second.
Step-by-Step Multiplication
First, we multiply x times x, which gives us x squared.
Next, we multiply the outer terms: x times positive y is plus xy.
Then, the inner terms: negative y times x gives us minus xy.
