All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.

This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x

Then combine like terms and line all the values in order from greatest exponent value to least to get 
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6

Hope this helped :)

The first step is to distribute the negative sign to the expression (x3+4x4+2x2-10x) and after distributing the negative sign, the expression will become (-x3-4x4-2x2+10x). Then combine this with the first given expression (3x5+3x2−4x3+x−6) and this will become 3x5+3x2−4x3+x−6-x3-4x4-2x2+10x. then you can simplify it into 3x5-4x4+5x3+x2+11x-6.
