Transcript text: $\int\left(e^{x}-e^{2 x}\right)^{2} d x$
Solution
To solve the integral \(\int\left(e^{x}-e^{2 x}\right)^{2} d x\), we can expand the integrand and then integrate term by term. First, expand \((e^{x} - e^{2x})^2\) to get a polynomial expression. Then, integrate each term separately.
Paso 1: Expansión del integrando
Para resolver la integral \(\int\left(e^{x}-e^{2 x}\right)^{2} d x\), primero expandimos el integrando:
\[
(e^{x} - e^{2x})^2 = e^{2x} - 2e^{3x} + e^{4x}
\]
Combinamos los resultados de las integrales individuales:
\[
\int\left(e^{x}-e^{2 x}\right)^{2} d x = \frac{e^{4x}}{4} - \frac{2e^{3x}}{3} + \frac{e^{2x}}{2} + C
\]
donde \(C\) es la constante de integración.
