Serena knows she can hit a golf ball two times as far with her driver as with her 9-iron. Write an expression in terms of x to represent how far Serena can hit a ball using her driver.
Use the Distributive Property to expand the expression you obtained in part B

Let’s try something a bit different. Serena hit a ball 2x yards past the 150-yard marker with her 3-iron. Write an expression in terms of x that represents this distance.

Now use the Distributive Property to factor the expression you obtained in part D.

Why do you think the operation that you performed on the expression in part E is called factoring? Use what you know about factoring numbers.
