#112x^4+240x^3-351x^2-375x+275#

Explanation:

In order to multiply #(11-15x-7x)(25-16x^2)# using tables, we have to make a 3x2 table and multiply the elements of each row to its corresponding column with their arithmetic sign.
After this simply aggregate each element and simplify the sums.

I am attaching an image of the solution since I couldn't draw the table.
