ayuda por favor :3​

Answer 1

Respuesta:

holii si la respuesta es =-2/r

Explicación paso a paso:

\frac{p}{r\left(r-p\right)}-\frac{1}{r}-\frac{1}{r-p}

\frac{p}{r\left(r-p\right)}-\frac{1}{r}-\frac{1}{r-p}

\frac{p-\left(r-p\right)-r}{r\left(r-p\right)}

\frac{2p-2r}{r\left(r-p\right)}

\frac{2\left(p-r\right)}{r\left(r-p\right)}

-2/r
