                  x²   +     x         + 7

 x²  +  1  √ x⁴ + x³  + 8x² + ax + b

                 x⁴         +   x²  

                         x³   + 7x²  + ax

                        x³                  x    

                                 + 7x² +   0    + b

                                   7x²  +         + 7    

                                                         0


  ax - x = 0

So a = 1  

b - 7 = 0  

b = 7
