Guess is, you really mean this expression: %28x%5E2+%2B+3x+%2B+1%29%28x%5E2+%2B+x+%2B+2%29;

and this grid:

_________x^2________3x_________1
-
x^2_____x^4________3x^3________x^2
-
x_______x^3________3x^2________x
-
2_______2x^2_______6x__________2


The top row is for the first polynomial factor and the leftmost column is for the second polynomial factor. Form the sum of the resulting terms and simplify showing in decreasing powers of x. Notice the diagonal arrangement of the individual powers of x in the interior cells of the grid!

"drag & drop" grid...
Do you have nine items to place or do you have four items to place?
If you have a GRID, then you must have an arrangement like I have illustrated and should include NINE interior cells, maybe also three more cells to make the left column for one polynomial factor and the three more cells to make the upper row for the other polynomial factor. Otherwise, explain your grid.
