+118609 two numbers which add to give 5 and multiply to give -14.
These are hard till you get the hang of them.
Look at the sign of the multiply first. it is negative, which means that one number must be + and the other is -
Now they add to a positive number. That means that the bigger one is positive.
Look at the multiply again.
14 = -1 * +14 14 = -2 * +7
there are no other integer possibilities.
-1+14=13 that is no good
-2+7 = 5 BINGO
