Explicación paso a paso:
[tex]P(x)=\frac{3x-5}{5x-3}[/tex]
[tex]P(P(x)) = P(\frac{3x-5}{5x-3} )[/tex]
[tex]= \frac{3(\frac{3x-5}{5x-3})-5 }{5(\frac{3x-5}{5x-3})-3 } = \frac{\frac{9x-15}{5x-3}-5 }{\frac{15x-25}{5x-3} -3}[/tex]
[tex]= \frac{\frac{9x-15-25x+15}{5x-3} }{\frac{15x-25-15x+9}{5x-3} } =\frac{-16x}{-16}[/tex]
[tex]= x[/tex]
[tex]Luego: P(P(x)) = x[/tex]
