Riješi x5/12-2/x-11

$$\frac { x 5 } { 12 } - \frac { 2 } { x - 11 }$$

Procijeni

$$\frac{xx_{5}-11x_{5}-24}{12\left(x-11\right)}$$

Kratki koraci rješenja

Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Najmanji zajednički množilac brojeva 12 i x-11 je 12\left(x-11\right). Pomnožite \frac{x_{5}}{12} i \frac{x-11}{x-11}. Pomnožite \frac{2}{x-11} i \frac{12}{12}.

$$\frac{x_{5}\left(x-11\right)}{12\left(x-11\right)}-\frac{2\times 12}{12\left(x-11\right)}$$

Pošto \frac{x_{5}\left(x-11\right)}{12\left(x-11\right)} i \frac{2\times 12}{12\left(x-11\right)} imaju isti imenilac, oduzmite ih tako što ćete oduzeti njihove brojioce.

$$\frac{x_{5}\left(x-11\right)-2\times 12}{12\left(x-11\right)}$$

Izvršite množenja u x_{5}\left(x-11\right)-2\times 12.

$$\frac{x_{5}x-11x_{5}-24}{12\left(x-11\right)}$$

Proširite 12\left(x-11\right).

$$\frac{x_{5}x-11x_{5}-24}{12x-132}$$

Faktor

$$\frac{xx_{5}-11x_{5}-24}{12\left(x-11\right)}$$
