The indefinite integral of $2x$ is $x^2+C$. In this context, the term 'indefinite integral' is simply another name for the antiderivative, representing the family of all functions whose derivative is $2x$.

Conditions: The expression being integrated is $2x$.; The result includes an arbitrary constant $C$.

The general form of the antiderivative of $2x$ is $x^2+C$, where $C$ represents an arbitrary constant. This is because multiple functions differing only by a constant share the same derivative.
