\frac{x^{2}+x}{\left(x-5\right)\left(x+5\right)}+\frac{x^{2}-1}{\left(x+5\right)\left(x+6\right)}
Faktorirajte x^{2}-25. Faktorirajte x^{2}+11x+30.
\frac{\left(x^{2}+x\right)\left(x+6\right)}{\left(x-5\right)\left(x+5\right)\left(x+6\right)}+\frac{\left(x^{2}-1\right)\left(x-5\right)}{\left(x-5\right)\left(x+5\right)\left(x+6\right)}
Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Najmanji zajednički množilac brojeva \left(x-5\right)\left(x+5\right) i \left(x+5\right)\left(x+6\right) je \left(x-5\right)\left(x+5\right)\left(x+6\right). Pomnožite \frac{x^{2}+x}{\left(x-5\right)\left(x+5\right)} i \frac{x+6}{x+6}. Pomnožite \frac{x^{2}-1}{\left(x+5\right)\left(x+6\right)} i \frac{x-5}{x-5}.
\frac{\left(x^{2}+x\right)\left(x+6\right)+\left(x^{2}-1\right)\left(x-5\right)}{\left(x-5\right)\left(x+5\right)\left(x+6\right)}
Pošto \frac{\left(x^{2}+x\right)\left(x+6\right)}{\left(x-5\right)\left(x+5\right)\left(x+6\right)} i \frac{\left(x^{2}-1\right)\left(x-5\right)}{\left(x-5\right)\left(x+5\right)\left(x+6\right)} imaju isti imenilac, saberite ih tako što ćete sabrati njihove brojioce.
\frac{x^{3}+6x^{2}+x^{2}+6x+x^{3}-5x^{2}-x+5}{\left(x-5\right)\left(x+5\right)\left(x+6\right)}
Izvršite množenja u \left(x^{2}+x\right)\left(x+6\right)+\left(x^{2}-1\right)\left(x-5\right).
\frac{2x^{3}+2x^{2}+5x+5}{\left(x-5\right)\left(x+5\right)\left(x+6\right)}
Kombinirajte slične izraze u x^{3}+6x^{2}+x^{2}+6x+x^{3}-5x^{2}-x+5.
\frac{2x^{3}+2x^{2}+5x+5}{x^{3}+6x^{2}-25x-150}
Proširite \left(x-5\right)\left(x+5\right)\left(x+6\right).
