\frac{\left(3x+1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)}+\frac{4x\left(x+1\right)}{\left(x+1\right)\left(x+2\right)}
Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Najmanji zajednički množilac brojeva x+1 i x+2 je \left(x+1\right)\left(x+2\right). Pomnožite \frac{3x+1}{x+1} i \frac{x+2}{x+2}. Pomnožite \frac{4x}{x+2} i \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)}
