1.) x+2 | 7x^3 - 6x^2 - 3x -> 7x^2

-( 7x^3 +14x^2 )

x+2 | -20x^2 - 3x -> -20x

-(20x^2 - 40x)

x+2 | 37x -> 37

-(37x + 74)

x+2 | -74 -> -74/(x+2)

(7x^3 - 6x^2 - 3x)/(x+2) = 7x^2 - 20x + 37 - 74/(x+2)

2.) x-4 | 3x^3 - 7x - 6 -> 3x^2

-(4x^3 - 12x^2)

x-4 | 12x^2 -7x - 6 -> 12x

-(12x^2 - 48x)

x-4 | 41x - 6 -> 41

-(141x - 164)

x-4| 158 -> 158/(x-4)

(3x^3 - 7x - 6) / (x-4) = 3x^2 + 12x + 41 + 158/(x-4)
