Divide x4 + 7 by x-3.

x^3   +  3x^2    +   9x    +  27   +   88 / [x - 3]

Step-by-step explanation:

x ^4 + 7 by x - 3 x^3   +  3x^2    +   9x        +  27 x - 3  [  x^4  +   0x^3    +   0x^2    +   0x    +   7   ]. x^3  -    

3x^3 3x^3   +     0x^2 3x^2  

-     9x^2 9x^2      +   0x 9x^2

   -    27x 27x    +   7 27x  

 -  81 88 S

 So the result is :      x^3   +  3x^2    +   9x    +  27   +   88 / [x - 3]
