  # Polynomial Factorization - Series 2c
  
  FACTORING BINOMIALS USING DIFFERENCE OF TWO SQUARES
  
  Binomials of the general form m^2 - n^2 can be factored into terms
  
  (m - n)*(m + n).
  
  example5:
  9x^2 - 64 = (3x)^2 - (8)^2
  = (3x-8)*(3x+8)
  
  example6:
  4a^3 - 4a = 4a * (a^2 -1)
  = 4a * (a^2 - 1^2)
  = 4a * (a - 1)(a + 1)
  
  example7:
  x^4 - y^4 = (x^2)^2 - (y^2)^2
  = (x^2 - y^2) * (x^2 + y^2)
  = (x - y)*(x +y) *(x^2 +y^2)
  
  FACTORING BINOMIALS USING SUM AND DIFFERENCE OF TWO CUBES
  
  Binomials of the general form outlined below can be factored as described:
  
  a^3 + b^3 can be factored into (a + b) * (a^2 - ab + b^2)
  a^3 - b^3 can be factored into (a - b) * (a^2 + ab + b^2)
