A)

Let’s simplify the expression! First, combine the like terms and . That gives us . Now, adding the constant back in, we get the final expression: . Voila! It’s all tidied up.

Now, if you’d like to factor it out, you can pull out a common factor. Notice that both terms share a factor of : . And even better, you can recognize that is a difference of squares, which factors to ! So there you go—a neat and tidy result.
