\frac{x+5}{\left(x+1\right)\left(x+2\right)\left(x+5\right)}+\frac{x+1}{\left(x+1\right)\left(x+2\right)\left(x+5\right)}
Če želite prišteti ali odšteti izraze, jih razširite na skupne imenovalce. Najmanjši skupni mnogokratnik \left(x+1\right)\left(x+2\right) in \left(x+2\right)\left(x+5\right) je \left(x+1\right)\left(x+2\right)\left(x+5\right). Pomnožite \frac{1}{\left(x+1\right)\left(x+2\right)} s/z \frac{x+5}{x+5}. Pomnožite \frac{1}{\left(x+2\right)\left(x+5\right)} s/z \frac{x+1}{x+1}.
\frac{x+5+x+1}{\left(x+1\right)\left(x+2\right)\left(x+5\right)}
\frac{x+5}{\left(x+1\right)\left(x+2\right)\left(x+5\right)} in \frac{x+1}{\left(x+1\right)\left(x+2\right)\left(x+5\right)} imata isti imenovalec, zato ju seštejte tako, da seštejete njuna števca.
\frac{2x+6}{\left(x+1\right)\left(x+2\right)\left(x+5\right)}
Združite podobne člene v x+5+x+1.
\frac{2x+6}{x^{3}+8x^{2}+17x+10}
Razčlenite \left(x+1\right)\left(x+2\right)\left(x+5\right).
