Če želite prišteti ali odšteti izraze, jih razširite na skupne imenovalce. Najmanjši skupni mnogokratnik x+1 in x+2 je \left(x+1\right)\left(x+2\right). Pomnožite \frac{3x+1}{x+1} s/z \frac{x+2}{x+2}. Pomnožite \frac{4x}{x+2} s/z \frac{x+1}{x+1}.
\frac{\left(3x+1\right)\left(x+2\right)+4x\left(x+1\right)}{\left(x+1\right)\left(x+2\right)}
\frac{\left(3x+1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)} in \frac{4x\left(x+1\right)}{\left(x+1\right)\left(x+2\right)} imata isti imenovalec, zato ju seštejte tako, da seštejete njuna števca.
\frac{3x^{2}+6x+x+2+4x^{2}+4x}{\left(x+1\right)\left(x+2\right)}
Izvedi množenje v \left(3x+1\right)\left(x+2\right)+4x\left(x+1\right).
