Issolvi x-1/x-x/x-1

$$\frac { x - 1 } { x } - \frac { x } { x - 1 }$$

Evalwa

$$\frac{1-2x}{x\left(x-1\right)}$$

Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' x u x-1 huwa x\left(x-1\right). Immultiplika \frac{x-1}{x} b'\frac{x-1}{x-1}. Immultiplika \frac{x}{x-1} b'\frac{x}{x}.

$$\frac{\left(x-1\right)\left(x-1\right)}{x\left(x-1\right)}-\frac{xx}{x\left(x-1\right)}$$

Billi \frac{\left(x-1\right)\left(x-1\right)}{x\left(x-1\right)} u \frac{xx}{x\left(x-1\right)} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{\left(x-1\right)\left(x-1\right)-xx}{x\left(x-1\right)}$$

Agħmel il-multiplikazzjonijiet fi \left(x-1\right)\left(x-1\right)-xx.

$$\frac{x^{2}-x-x+1-x^{2}}{x\left(x-1\right)}$$

Ikkombina termini simili f'x^{2}-x-x+1-x^{2}.

$$\frac{-2x+1}{x\left(x-1\right)}$$

Espandi x\left(x-1\right).

$$\frac{-2x+1}{x^{2}-x}$$

Espandi
