Which of the following is the product of two integers whose sum is 12?	Choose the correct choice from the following options.
A) -42  B) -28  C) 12  D) 26  E) 32
I solved this Question like this,   Let the two integers are x,y   x+y=12 (Given)   xy=? (Needed)   instead of solving this algebraically, Test the Answer choices   B. -28   Do the factorization : (-1,28)----&gt; There sum is not 12--eliminate   (-2,14)----&gt;There sum is 12 Bingo!!!!   So, my answer is B...   As the answer is in B, it took me very less time to answer the question. but i think this method is be simple and efficient.
