\frac{x-1}{\left(x+1\right)\left(x+3\right)}+\frac{2}{\left(x+2\right)\left(x+3\right)}
Faktorizirajte x^{2}+4x+3. Faktorizirajte x^{2}+5x+6.
\frac{\left(x-1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}+\frac{2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Če želite prišteti ali odšteti izraze, jih razširite na skupne imenovalce. Najmanjši skupni mnogokratnik \left(x+1\right)\left(x+3\right) in \left(x+2\right)\left(x+3\right) je \left(x+1\right)\left(x+2\right)\left(x+3\right). Pomnožite \frac{x-1}{\left(x+1\right)\left(x+3\right)} s/z \frac{x+2}{x+2}. Pomnožite \frac{2}{\left(x+2\right)\left(x+3\right)} s/z \frac{x+1}{x+1}.
