\frac{7x+6}{\left(x-1\right)\left(x+1\right)}-\frac{x+6}{x-1}
Faktorirajte x^{2}-1.
\frac{7x+6}{\left(x-1\right)\left(x+1\right)}-\frac{\left(x+6\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)}
Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Najmanji zajednički množilac brojeva \left(x-1\right)\left(x+1\right) i x-1 je \left(x-1\right)\left(x+1\right). Pomnožite \frac{x+6}{x-1} i \frac{x+1}{x+1}.
\frac{7x+6-\left(x+6\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)}
Pošto \frac{7x+6}{\left(x-1\right)\left(x+1\right)} i \frac{\left(x+6\right)\left(x+1\right)}{\left(x-1\right)\left(x+1\right)} imaju isti imenilac, oduzmite ih tako što ćete oduzeti njihove brojioce.
\frac{7x+6-x^{2}-x-6x-6}{\left(x-1\right)\left(x+1\right)}
Izvršite množenja u 7x+6-\left(x+6\right)\left(x+1\right).
\frac{-x^{2}}{\left(x-1\right)\left(x+1\right)}
Kombinirajte slične izraze u 7x+6-x^{2}-x-6x-6.
\frac{-x^{2}}{x^{2}-1}
Proširite \left(x-1\right)\left(x+1\right).
