,Simplifique as expressoes: (x²-4x+4).(x+2): x²-4 e x³+y³: x³-x²y+xy²,(x³-x²y+xy²≠0)
(x² - 4x + 4)(x + 2): x² - 4 =
(x² - 4x + 4)( x + 2)
---------------------------- =
x² - 4
(x - 2)(x - 2)(x + 2)
-----------------------------------
x² - 4
(x - 2)(x² + 2x - 2x - 4)
-------------------------------------
x² - 4
(x - 2)(x² 0 - 4)
---------------------------------------
x² - 4
(x - 2)(x² - 4)
---------------------------
x² - 4 =
(x - 2)(x² - 4) : (x² - 4)
--------------------------------- = ( x - 2)
( x² - 4) : (x² - 4)
x³+y³: x³-x²y+xy²
x³ + y³
--------------------------
x³ - x²y + xy².
(x² - 4x + 4)(x + 2): x² - 4 =
(x² - 4x + 4)( x + 2)
---------------------------- =
x² - 4
(x - 2)(x - 2)(x + 2)
-----------------------------------
x² - 4
(x - 2)(x² + 2x - 2x - 4)
-------------------------------------
x² - 4
(x - 2)(x² 0 - 4)
---------------------------------------
x² - 4
(x - 2)(x² - 4)
---------------------------
x² - 4 =
(x - 2)(x² - 4) : (x² - 4)
--------------------------------- = ( x - 2)
( x² - 4) : (x² - 4)
x³+y³: x³-x²y+xy²
x³ + y³
--------------------------
x³ - x²y + xy².
