Wykonaj dzielenie wielomianów:
a) (2xdo3-3xdo2-5x+6):(x-2)
b) (2xdo4-3xdo3-7xdo2+5x-3):(2xdo2+x-3)
a)
(2x³ - 3x² - 5x + 6) : (x - 2) = 2x² + x - 3
-2x³ + 4x²
------------
x² - 5x + 6
- x² + 2x
-----------
- 3x + 6
+ 3x - 6
----------
R = 0
b)
(2x⁴ - 3x³ - 7x² + 5x - 3) : (2x² + x - 3) = x² - 2x - 1
-2x⁴ - x³ + 3x²
-----------------
- 4x³ - 4x² + 5x - 3
+4x³ + 2x² - 6x
-----------------------
- 2x² - x - 3
+ 2x² + x - 3
----------------
R = - 6
