  1. (6x^4-4x^2+3x-2):(3x-2)
     = ( 6x^4 : 3x ) – ( 6x^4 : 2 ) – ( 4x^2 : 3x ) + ( 4x^2 : 2 ) + ( 3x : 2 ) – ( 2 : 3x ) + ( 2 : 2 )
    =  2x^3 – 3x^4 – 4/3x + 2x^2 – 1,5x – 2/3x + 1
    =  2x^3 – 3x^4 + ( -4/3x – 1,5x – 2/3x ) + 2x^2 + 1
    =  -3x^4 + 2x^3 + 2x^2 – 3,5x + 1

  2. (6x^4 – 4x^2 + 3x – 2) : (3x – 2)
    = 6x^4 : 3x – 6x^4 : 2 – 4x^2 : 3x + 4x^2 : 2 + 3x : 3x – 3x : 2 – 2 : 3x + 2 : 2
    = 2x^3 – 3x^4 – 4/3x + 2x^2 – 1,5x – 2/3x + 1
    = 2x^3 – 3x^4 + (-4/3x – 1,5x – 2/3x) + 2x^2 + 1
    = – 3x^4 + 2x^3 + 2x^2 – 3,5x + 1
