Question

Suppose A and B represent two different school populations where A > B and A and B must be greater than 0. Which of the following expressions is the largest? Explain why. Show all work necessary.
A: 2(A + B)
B: (A + B)^2
C: A^2 + B^2
D: A^2 − B^2

Answer 1

C. A^2 +B^2 will be the largest because we know that (a+b)^2 = a^2 +2ab +b^2

so than you check these other choices this ie the largest sure 

hope this will help you
