¡La respuesta!

La respuesta es

$\tt{x = \frac{6 + i \sqrt{39} }{3}, \frac{6 - i \sqrt{39 }{3}$ Vamos a revisar

$\tt log2 + log(x - {x}^{2} ) = 2log(5 - x) \\ = \tt log(2x - {2x}^{2} ) = 2log(5 - x) \\ = \tt log(2x - {2x}^{2} ) = 2log((5 - x) {}^{2} ) \\ = \tt 2x - {2x}^{2} = ( {5 - x)}^{2} \\ = \tt\large\boxed{\tt{\green{x = \frac{6 + i \sqrt{39} }{3}, \frac{6 - i \sqrt{39} }{3} }}}$

Tenemos razón, puedes copiar eso :)
