  Solve:
  
  2x^-2 - 5x^-1 - 3 = 0
  
  2a^2 -5a - 3 = 0
  
  (2a^2 - ) + ( a - ) = 0

  is 2a^2 -5a - 3 = 0
  supposed to be the simplified version of
  2x^-2 - 5x^-1 - 3 = 0 ??
  
  2/x^2 - 5/x - 3 = 0
  multiply each term by x^2
  2 - 5x - 3x^2 = 0
  3x^2 + 5x - 2 = 0
  (3x-1)(x+2) = 0
  x = 1/3 or x = -2

  yes that is the sinplified version of
