Divide the following polynomials using synthetic division, then place the answer in the proper location on the grid. write answer in descending powers of x. (x4 + 81) (x + 3)

X^4-81=     x^4+0x^3+0x^2+0x-81
       
              !   1       0        0       0   -81
x+3→-3 !           -3        9    -27    81
         
                  1      -3        9    -27      0

                 x^3-3x^2+9x-27
