B)

Did you know that the expression is a perfect square trinomial? When you expand it, you’ll get . Perfect square trinomials are formed by squaring a binomial and are super useful for factoring and solving quadratic equations!

Now, let’s talk about real-world applications! The formula for expanding is often used in finance and engineering when calculating areas or when two variables interact with each other. For instance, if you’re working on optimizing a rectangular garden plot represented by the dimensions , squaring that will give you the area, making it easier to plan your landscaping or planting!
