so if you were going to evaluate the indefinite integral that would need a variable factored in by the u subtitution method how is it done without expansion and term by term integration?

for instance:

Integrand: (2x^2)^2

let U = 2x^2

dU=(4x)dx

the problem is that the varaible "x" cannot be brought outside the inteegral so how does one "massage it".. so to speak

perhaps this method isnt workable for this type of integrand?
