1) Cancel out the common factor which in this case is 8 
2)First apply exponent rule
now cancel out the common factors which are n and n+7 leaving you with 
3)Factorize
cancel out the common factor in this case x+2 leaving you with 
4) Factorize
cancel out the common factor in this case 3w-1 leaving you with
