Problem:

Find an indefinite integral (which can vary by a constant) of the following function:

$\frac{2 x^2 \left(49 x^4+42 x+15\right)}{\left(2 x^3+3\right) \left(7 x^4+5\right)}$

from sympy import *

x = symbols('x')
f = ((2*x**2*(49*x**4+42*x+15))/((2*x**3+3)*(7*x**4+5)))
print(integrate(f, x))
