Hi,
Two negative integers 'x' and 'y' have a sum of -12 and a product or 11. 
What are the integers? 
 xy = 11  0r   x = 11/y
   {{{11/y + y = -12}}}    ||Multiplying thru by y  so as all denominators = 1
   11 + y^2 = -12y
    y^2 + 12y + 11 = 0
  (y+11)(y+1) = 0
  (y+11)= 0  , y = -11  , x = -1
0r(y+1) = 0  , y = -1   , x = -11
 Integers are:  -11, -1

Sum of -12  and product of 11
