Para resolver la ecuación diferencial ordinaria y' - y = 0 utilizando el método de series de potencias, asumimos que la solución tiene la forma de una serie de potencias alrededor de un punto x_0:

y(x) = \sum_{n=0}^{\infty} a_n (x - x_0)^n

Calculamos la derivada primera de y(x) con respecto a x:

y'(x) = \sum_{n=0}^{\infty} n \cdot a_n \cdot (x - x_0)^{n-1}

Sustituimos y(x) y y'(x) en la ecuación diferencial dada:

\sum_{n=0}^{\infty} n \cdot a_n \cdot (x - x_0)^{n-1} - \sum_{n=0}^{\infty} a_n \cdot (x - x_0)^n = 0

Reorganizamos la expresión y comparamos los términos con el término independiente:

n \cdot a_n \cdot (x - x_0)^{n-1} - a_n \cdot (x - x_0)^n = 0

n \cdot a_n \cdot (x - x_0)^{n-1} - a_n \cdot (x - x_0)^n = 0

Para que los términos se anulen, debemos tener:

n \cdot a_n = a_n \Rightarrow a_n (n - 1) = 0

Esto se cumple cuando n = 1, por lo que a_1 = a_1(1-1) = 0. Por lo tanto, a_n = 0 para n > 1.

La solución a la ecuación diferencial y' - y = 0 a través de series de potencia es:

y(x) = a_0 + a_1(x - x_0)

donde a_0 y a_1 son constantes arbitrarias.

\boxed{y(x) = a_0 + a_1x}
