Datrys x-1/x^2-x+1

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

Enrhifo

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

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch -x+1 â \frac{x^{2}}{x^{2}}.

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

Gan fod gan \frac{x-1}{x^{2}} a \frac{\left(-x+1\right)x^{2}}{x^{2}} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

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

Gwnewch y gwaith lluosi yn x-1+\left(-x+1\right)x^{2}.

$$\frac{x-1-x^{3}+x^{2}}{x^{2}}$$
