разделить уголком 4x^4-12x^2+13x ** x+2

Question

разделить уголком 4x^4-12x^2+13x на x+2

Answer 1

4x^4  -  12x^2  + 13x |   x+2
4x^4 + 8x^3               4x^3 - 8x^2 + 4x + 5
- 8x^3 -  12x^2  + 13x
- 8x^3  -  16x^2
               4x^2  + 13x
               4x^2  +  8 x
                            5x
                            5х+10
                                  -10

4x^4-12x^2+13x : x+2  =  4x^3 - 8x^2 + 4x + 5 -  10/(x+2)
