I'll give you a question, please answer with step-by-step reasoning process.
Four of the five parts numbered (a), (b), (c), (d) and (e) in the following equation are exactly equal. Which part is not equal to the other four ? The number of that part is the answer.\nOptions:\n(A) (x + 2y) (3x + 2y) \n(B) (x + 2y) 2 + 2x(x + 2y) \n(C) (3x + 2y) 2 – 2x(3x + 2y) \n(D) 3x(x + 2y)  + 2y(x + 2y) \n(E) x(3x + 2y)  – 2y(3x – 2y) 

(E)
Others are equal to 3x2 + 8xy + 4y2.

So, the answer is (E)
