Answer:

5x^4 -7x^3-5x^2+5x+1

Step-by-step explanation:

You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.

Hope this helps!
