Luacháil

$$\frac{7x^{2}}{12}-\frac{y^{2}}{6}-\frac{z^{2}}{12}$$

Céimeanna Réitigh

Comhcheangail -\frac{1}{2}y^{2} agus \frac{1}{3}y^{2} chun -\frac{1}{6}y^{2} a fháil.

$$\frac{3}{4}x^{2}-\frac{1}{6}y^{2}-\frac{1}{3}z^{2}+\frac{1}{4}z^{2}-\frac{1}{6}x^{2}$$

Comhcheangail -\frac{1}{3}z^{2} agus \frac{1}{4}z^{2} chun -\frac{1}{12}z^{2} a fháil.

$$\frac{3}{4}x^{2}-\frac{1}{6}y^{2}-\frac{1}{12}z^{2}-\frac{1}{6}x^{2}$$

Comhcheangail \frac{3}{4}x^{2} agus -\frac{1}{6}x^{2} chun \frac{7}{12}x^{2} a fháil.

$$\frac{7}{12}x^{2}-\frac{1}{6}y^{2}-\frac{1}{12}z^{2}$$

Fachtóirigh

$$\frac{7x^{2}-2y^{2}-z^{2}}{12}$$

Céimeanna Réitigh

Fág \frac{1}{12} as an áireamh.

$$\frac{9x^{2}-6y^{2}-4z^{2}+4y^{2}+3z^{2}-2x^{2}}{12}$$
