irina1246 [14]
Let's rewrite the expression correctly:
 (12x3 - 11x2 + 22x - 5) / (4x -1)
 Dividing the expression between (4x -1) we have:
 3x2 - 2x + 5
 We can check the result:
 (3x2 - 2x + 5) * (4x-1)
 = 12x3 - 8x2 + 20x - 3x2 + 2x - 5
 = 12x3 - 11x2 + 22x - 5
 Division OK.
 Answer:
 
The result of the division is:
 
3x2 - 2x + 5
