$$-\frac{2}{y-x}x^3-x^2-xy-y^2$$or
$$\frac{2}{x-y}x^3-x^2-xy-y^2$$

anonymous · Answer

man you fight with that machine easy lol

anonymous · Answer

$$y^2-xy-x^2-x^3\frac{ 2 }{ y-x }$$

anonymous · Answer

for it should be like that look on screen

amistre64 · Answer

thats ascending powers of x that way

anonymous · Answer

so im right?

anonymous · Answer

i started it doesn't fit -x^3 :/

anonymous · Answer

something wrong

amistre64 · Answer

long hand we get


         x^2+xy +y^2
     --------------------
x-y | x^3                   +y^3
       x^3-x^2y
      ----------
               x^2y
               x^2y-xy^2
              -----------
                        xy^2+y^3
                        xy^2-y^3
                       ----------
                           2y^3

amistre64 · Answer

$$x^2+xy+y^2+\frac{2y}{x-y}$$

amistre64 · Answer

2y^3 on that last part

amistre64 · Answer

synthetic gives us

      x^3+ 0+ 0   +y^3
     0       y    y^2   y^3
y    1       y   y^2   2y^3
     x^2   x

$$x^2+xy+y^2+\frac{2y^3}{x-y}$$

anonymous · Answer

x^2+xy+y^2+[ ]2y/x-y their is still one spot left

anonymous · Answer

need to be filled

anonymous · Answer

nvm your right its just me putting symbols wrong lol
