A) (5x₂+13x+11) : (x+2) = 5x+3
-5x²-10x
-------------
= 3x+11
-3x - 6
------------
= 5

b) (x³-3x²+3x-1) : (x-1) = x²-2x+1
-x³+x²
-------------
= -2x²+3x
2x² -2x
------------
= x-1
-x+1
------------
= =

c) (2x⁴+5x³+x²-2x):(x+2) = 2x³+x²-x
-2x⁴-4x³
---------------
= x³+x²
-x³-2x²
------------------
= -x²-2x
x² +2x
-----------------
= =
