1. x³+x²-x-1
----------------- = (x²-1)(x+1) / (x²-1)(x²-1) =(x+1)/(x²-1) = (x+1)/(x-1)(x+1)
x⁴-2x²+1

=1/(x-1)

x³+x²-x-1 : (x²-1) = x + 1
-x³+x
x² -1


2. x²+x-6
----------------- = (x+3)(x-2) / (x-2)(x-2) = (x+3) / (x-2)
x²-4x+4

3. x²-8x+15
----------------- = (x-5)(x-3) / (x-3)(x-3) = (x-5) / (x-3)
x²-6x+9

4. x²+2x+1
----------------- = (x+1)(x+1) / (x+1)(x+7) = (x+1) / (x+7)
x²+8x+7
