Answer 1

 4 - (x - 2)²             2² - (x - 2)²          [ 2 - (x - 2)][2 + (x - 2)]         (2 - x + 2)(2 + x - 2)

------------------ = -------------------- = ------------------------------- = --------------------------

16x - 8x² + x³      x(x² - 8x + 16)                 x(x - 4)²                           x(x - 4)(x - 4)

 

      (4 - x) * x                -(x - 4)                       -1

= -------------------- = -------------------  = ----------

      x(x - 4)(x - 4)         (x - 4)(x - 4)           x - 4

 

zał. x ≠ 0 i x ≠ 4
