SUMMARY
The discussion centers on the derivation of the Maclaurin series for the function \( f(x) = x^2 e^x \). The correct approach involves recognizing that the exponential function can be expressed as a power series, specifically \( e^x = \sum_{n=0}^{\infty} \frac{x^n}{n!} \). By substituting this into the expression for \( x^2 e^x \), the series simplifies to \( \sum_{n=0}^{\infty} \frac{x^{n+2}}{n!} \), confirming that this is indeed a Maclaurin series, which is a Taylor series expanded at the point \( 0 \).
