Answer 1

16x² - 9 y² =
√16x² - √9y² = ( 4x + 3y)(4x - 3y)
-----------------------------------------------

1/9 - 4² = (1/3 + 2)(1/3 - 2)
-----------------------------------------------------------

b² - 4/25 = (b + 2/5)(b - 2/5)
-----------------------------------------------------------

49h² - 81p² = (7h + 9p)(7h - 9p)
-------------------------------------------------------

1/100 - x²y² = (1/10 + xy)(1/10 - xy)
------------------------------------------------------------------------------

b² - c² = ( b + c)(b - c)
---------------------------------------------------------

1/25 - a²/4 = (1/5 + a/2)(1/5 - a/2)
----------------------------------------------------------

 4    4
x  - y  = (x² + y²)(x² - y²)
          = (x² + y²)(x + y)(x + y)
-------------------------------------------------------------

     4
a²b  -  x² = (ab² + x)(ab² - x)
------------------------------------------------------

  6    6
a  -  b  = (a³ + b³)(a³ - b³)
----------------------------------------------------------

  10                  5           5
x      - 100  = (x  + 10)(x  - 10)
--------------------------------------------------

  8             4          4
y    - 9 = (y   + 3)(y  - 3)
------------------------------------------

           4
y² - 81s  = (y + 9s²)(y - 9s²)
