C:

Did you know that the expression is a difference of squares? This means it can be factored efficiently using the formula . Here, you can think of as and as . So, it factors to !

In the real world, this mathematical concept is quite useful! For example, in physics, terms like might relate to projectile motion calculations, where understanding distances and heights can mean the difference between hitting your target or missing it entirely. Plus, factoring can help simplify complex equations that model these real-world scenarios!
