\frac{2\left(x-2\right)}{x-2}-\frac{x+1}{x-2}-\frac{x-4}{x+2}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Pomnožite 2 i \frac{x-2}{x-2}.
\frac{2\left(x-2\right)-\left(x+1\right)}{x-2}-\frac{x-4}{x+2}
Budući da \frac{2\left(x-2\right)}{x-2} i \frac{x+1}{x-2} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{2x-4-x-1}{x-2}-\frac{x-4}{x+2}
Pomnožite izraz 2\left(x-2\right)-\left(x+1\right).
\frac{x-5}{x-2}-\frac{x-4}{x+2}
Kombinirajte slične izraze u 2x-4-x-1.
\frac{\left(x-5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}-\frac{\left(x-4\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 x-2 i x+2 jest \left(x-2\right)\left(x+2\right). Pomnožite \frac{x-5}{x-2} i \frac{x+2}{x+2}. Pomnožite \frac{x-4}{x+2} i \frac{x-2}{x-2}.
\frac{\left(x-5\right)\left(x+2\right)-\left(x-4\right)\left(x-2\right)}{\left(x-2\right)\left(x+2\right)}
Budući da \frac{\left(x-5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)} i \frac{\left(x-4\right)\left(x-2\right)}{\left(x-2\right)\left(x+2\right)} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{x^{2}+2x-5x-10-x^{2}+2x+4x-8}{\left(x-2\right)\left(x+2\right)}
Pomnožite izraz \left(x-5\right)\left(x+2\right)-\left(x-4\right)\left(x-2\right).
\frac{3x-18}{\left(x-2\right)\left(x+2\right)}
Kombinirajte slične izraze u x^{2}+2x-5x-10-x^{2}+2x+4x-8.
\frac{3x-18}{x^{2}-4}
Proširivanje broja \left(x-2\right)\left(x+2\right).
\frac{2\left(x-2\right)}{x-2}-\frac{x+1}{x-2}-\frac{x-4}{x+2}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Pomnožite 2 i \frac{x-2}{x-2}.
\frac{2\left(x-2\right)-\left(x+1\right)}{x-2}-\frac{x-4}{x+2}
Budući da \frac{2\left(x-2\right)}{x-2} i \frac{x+1}{x-2} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{2x-4-x-1}{x-2}-\frac{x-4}{x+2}
Pomnožite izraz 2\left(x-2\right)-\left(x+1\right).
\frac{x-5}{x-2}-\frac{x-4}{x+2}
Kombinirajte slične izraze u 2x-4-x-1.
\frac{\left(x-5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}-\frac{\left(x-4\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 x-2 i x+2 jest \left(x-2\right)\left(x+2\right). Pomnožite \frac{x-5}{x-2} i \frac{x+2}{x+2}. Pomnožite \frac{x-4}{x+2} i \frac{x-2}{x-2}.
\frac{\left(x-5\right)\left(x+2\right)-\left(x-4\right)\left(x-2\right)}{\left(x-2\right)\left(x+2\right)}
Budući da \frac{\left(x-5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)} i \frac{\left(x-4\right)\left(x-2\right)}{\left(x-2\right)\left(x+2\right)} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.
\frac{x^{2}+2x-5x-10-x^{2}+2x+4x-8}{\left(x-2\right)\left(x+2\right)}
Pomnožite izraz \left(x-5\right)\left(x+2\right)-\left(x-4\right)\left(x-2\right).
\frac{3x-18}{\left(x-2\right)\left(x+2\right)}
Kombinirajte slične izraze u x^{2}+2x-5x-10-x^{2}+2x+4x-8.
\frac{3x-18}{x^{2}-4}
Proširivanje broja \left(x-2\right)\left(x+2\right).
