Four of the five parts numbered as (a), (b), (c), (d) and (e)in the following equations are exactly equal. You have to find out the part that is not equal to the other parts. The number of that part is the answer.  Pick:  A) a2 + 5ab + 6b2  B) (a + 3b)(a + 2b)  C) a(a + 3b) + 2b(a + 3b)  D) (3a + b)(a + 2b)  E) a(a + 2b) + 3b(a + 2b)
The other parts are equal to a2 + 5ab + 6b2.   Answer (3a + b)(a + 2b)
