\frac{4}{\left(x+2\right)\left(x+3\right)}+\frac{x-2}{x+3}
Rastavite x^{2}+5x+6 na faktore.
\frac{4}{\left(x+2\right)\left(x+3\right)}+\frac{\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva \left(x+2\right)\left(x+3\right) i x+3 jest \left(x+2\right)\left(x+3\right). Pomnožite \frac{x-2}{x+3} i \frac{x+2}{x+2}.
\frac{4+\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)}
Budući da \frac{4}{\left(x+2\right)\left(x+3\right)} i \frac{\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)} imaju isti nazivnik, zbrojite ih zbrajanjem njihovih brojnika.
\frac{4+x^{2}+2x-2x-4}{\left(x+2\right)\left(x+3\right)}
Pomnožite izraz 4+\left(x-2\right)\left(x+2\right).
\frac{x^{2}}{\left(x+2\right)\left(x+3\right)}
Kombinirajte slične izraze u 4+x^{2}+2x-2x-4.
\frac{x^{2}}{x^{2}+5x+6}
Proširivanje broja \left(x+2\right)\left(x+3\right).
\frac{4}{\left(x+2\right)\left(x+3\right)}+\frac{x-2}{x+3}
Rastavite x^{2}+5x+6 na faktore.
\frac{4}{\left(x+2\right)\left(x+3\right)}+\frac{\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva \left(x+2\right)\left(x+3\right) i x+3 jest \left(x+2\right)\left(x+3\right). Pomnožite \frac{x-2}{x+3} i \frac{x+2}{x+2}.
\frac{4+\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)}
Budući da \frac{4}{\left(x+2\right)\left(x+3\right)} i \frac{\left(x-2\right)\left(x+2\right)}{\left(x+2\right)\left(x+3\right)} imaju isti nazivnik, zbrojite ih zbrajanjem njihovih brojnika.
\frac{4+x^{2}+2x-2x-4}{\left(x+2\right)\left(x+3\right)}
Pomnožite izraz 4+\left(x-2\right)\left(x+2\right).
\frac{x^{2}}{\left(x+2\right)\left(x+3\right)}
Kombinirajte slične izraze u 4+x^{2}+2x-2x-4.
\frac{x^{2}}{x^{2}+5x+6}
Proširivanje broja \left(x+2\right)\left(x+3\right).
