By a change of variables, determine the indefinite integral as follows:
integral (x^2 - 3x^4)^1/2dx?
================================
The integrand can be factored as:
sqrt%28x%5E2%281+-+3x%5E2%29%29+=+x%2Asqrt%281-3x%5E2%29
Let y+=+1+-+3x%5E2
Then dy+=+-6x%2Adx
So the integral can be written as
%28-1%2F6%29%2Aint%28y%5E%281%2F2%29%2Cdy%29
