\frac{x+1}{\left(x-3\right)\left(x+3\right)}-\frac{x-1}{\left(x+3\right)^{2}}
Faktorizirajte x^{2}-9. Faktorizirajte x^{2}+6x+9.
\frac{\left(x+1\right)\left(x+3\right)}{\left(x-3\right)\left(x+3\right)^{2}}-\frac{\left(x-1\right)\left(x-3\right)}{\left(x-3\right)\left(x+3\right)^{2}}
Če želite prišteti ali odšteti izraze, jih razširite na skupne imenovalce. Najmanjši skupni mnogokratnik \left(x-3\right)\left(x+3\right) in \left(x+3\right)^{2} je \left(x-3\right)\left(x+3\right)^{2}. Pomnožite \frac{x+1}{\left(x-3\right)\left(x+3\right)} s/z \frac{x+3}{x+3}. Pomnožite \frac{x-1}{\left(x+3\right)^{2}} s/z \frac{x-3}{x-3}.
