  Factorize: a2 + 81
  
  It doesn't look like it in its current form, but this can be changed to be a difference of two squares which can then be factorize. However to do this, we will need to use complex numbers.
  
  a2 + 81
  
  = a2 - (9i)2
  
  = (a + 9i)(a - 9i)
  
  (where i is the square root of -1)
