\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{x+5}{x-2}
Rastavite x^{2}-4 na faktore.
\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva \left(x-2\right)\left(x+2\right) i x-2 jest \left(x-2\right)\left(x+2\right). Pomnožite \frac{x+5}{x-2} i \frac{x+2}{x+2}.
\frac{x+6-\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}
Budući da \frac{x+6}{\left(x-2\right)\left(x+2\right)} i \frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{x+6-x^{2}-2x-5x-10}{\left(x-2\right)\left(x+2\right)}
Pomnožite izraz x+6-\left(x+5\right)\left(x+2\right).
\frac{-6x-4-x^{2}}{\left(x-2\right)\left(x+2\right)}
Kombinirajte slične izraze u x+6-x^{2}-2x-5x-10.
\frac{-6x-4-x^{2}}{x^{2}-4}
Proširivanje broja \left(x-2\right)\left(x+2\right).
\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{x+5}{x-2}
Rastavite x^{2}-4 na faktore.
\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}

\frac{x+6-\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}
Budući da \frac{x+6}{\left(x-2\right)\left(x+2\right)} i \frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{x+6-x^{2}-2x-5x-10}{\left(x-2\right)\left(x+2\right)}
Pomnožite izraz x+6-\left(x+5\right)\left(x+2\right).
\frac{-6x-4-x^{2}}{\left(x-2\right)\left(x+2\right)}
Kombinirajte slične izraze u x+6-x^{2}-2x-5x-10.
\frac{-6x-4-x^{2}}{x^{2}-4}
Proširivanje broja \left(x-2\right)\left(x+2\right).
