Find the product of (x + 5)^2. a. x^2 − 10x + 25 b. x^2 − 25 c. x^2 + 25 d. x^2 + 10x + 25

D, because you have to FOIL (First, Outer, Inner, Last). (x + 5)^2 is also (x + 5) • (x + 5). Multiply the first two terms (x • x) you get x^2. Multiply the outer terms (x • 5) you get 5x. Multiply the inner terms (5 • x) you get 5x. Multiply the last terms (5 • 5) you get 25. Finally add all the terms together. (x^2 + 5x + 5x + 25)

I believe the answer is D
