1. The problem statement, all variables and given/known data Find the indefinite integral by substitution. ∫2x/(x+5)^6 dx 2. Relevant equations 3. The attempt at a solution I know how to do this using the method of partial fractions, but the book says to use substitution. Is there a way to just do a basic u-substitution with this integrand that I'm just not seeing? Or a way to solve without partial fractions? (we haven't gotten to partial fractions in my class so I feel like there must be some other way). Thanks!
