Step 1: Recognizing the error in the statement.
The given statement is incorrect. The integral \( \int dx \) represents the antiderivative of 1 with respect to \( x \). The correct antiderivative of 1 is \( x \), not \( x^2 \).
Step 2: Correcting the statement.
The correct result of \( \int dx \) is:
\[
\int dx = x + C
\]
where \( C \) is the constant of integration.
Step 3: Conclusion.
Thus, the statement is False, because the correct integral is \( \int dx = x + C \), not \( x^2 + C \).
