algebra precalculus - Finding a coefficient of x6 in the expansion (x1)5(x+1)5

Find the coefficient of x6 in the expansion (x1)5(x+1)5.



Is this question binomial? I understand the basiscs of the question but am unsure of how to complete the second part of the question.




Any assistance is greatly appreciated.



Thank you.
