  1. (a + b)2 = a2 + b2 + 2ab

  2. (a - b)2 = a2 + b2 - 2ab

  3. (a + b)2 + (a - b)2 = 2(a2 + b2)

  4. (a + b)2 - (a - b)2 = 4ab

  5. a2 - b2 = (a + b) (a - b)

  6. (a + b)3 = a3 + b3 + 3ab (a + b)

  7. (a - b)3 = a3 - b3 - 3ab (a - b)

  8. a3 + b3 = (a + b) (a2 - ab + b2)

  9. a3 - b3 = (a - b) (a2 + ab + b2)

  10. logax = y →ay = x

  11. logaxp = p logax

  12. logaxy = loga x + logay
