X²-2x-35 | x-7
x²-7x       x+5
   5x-35
   5x-35
        0
(x-7)(x+5)=x²-7x+5x-35= x²-2x-35

-4x²-x+5 | 4x+5
-4x²-5x -x+1
   4x+5
   4x+5
        0
(4x+5)(-x+1)=-4x²-5x+4x+5= -4x²-x+5

6x²+7x-3 | 2x+3
6x²+9x 3x-1
     -2x-3
     -2x-3
          0
(2x+3)(3x-1)=6x²+9x-2x-3=6x²+7x-3

6x³+7x²-6x+1 | 3x-1
6x³-2x²      2x²+3x-1
     9x²-6x
     9x²-3x
         -3x+1
          -3x+1
               0
(3x-1)( 2x²+3x-1)=6x³-2x²+9x²-3x-3x+1=6x³+7x²-6x+1

6x³+11x²   -1 | 2x²+3x-1
6x³+9x²-3x 3x+1
   2x²+3x-1
   2x²+3x-1
   0
( 2x²+3x-1)(3x-1) =6x³-2x²+9x²-3x-3x+1=6x³+7x²-6x+1

15x³-  x²+  8x-4 | 3x²+x+2
15x³+5x²+10x 5x-2
     -6x²-2x-4
     -6x²-2x-4
0
(3x²+x+2)(5x-2)=15x³-6x²+5x²-2x+10x-4=15x³-x²+8x-4
