Here is the original problem
%283x%5E2%2Bx-12%29%2B%282x%2B5-x%5E3%2B10x%5E2%29
we want to combine like terms and write in descending order . . .
first, we need to reorder everything in descending order as
-x%5E3%2B3x%5E2%2B10x%5E2%2Bx%2B2x-12+%2B+5
Now we can combine like terms to get
-x%5E3%2B13x%5E2+%2B3x+-7
