Question 260325
Here is the original problem
{{{(3x^2+x-12)+(2x+5-x^3+10x^2)}}}
we want to combine like terms and write in descending order . . .
first, we need to reorder everything in descending order as
{{{-x^3+3x^2+10x^2+x+2x-12 + 5}}}
Now we can combine like terms to get
{{{-x^3+13x^2 +3x -7}}}
