Réitigh m^2-13n+72=0

$$m ^ { 2 } - 13 n + 72 = 0$$

Réitigh do n.

$$n=\frac{m^{2}+72}{13}$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain m^{2} ón dá thaobh. Is ionann rud ar bith a dhealaítear ó nialas agus a shéanadh.

$$-13n+72=-m^{2}$$

Bain 72 ón dá thaobh.

$$-13n=-m^{2}-72$$

Roinn an dá thaobh faoi -13.

$$\frac{-13n}{-13}=\frac{-m^{2}-72}{-13}$$

Má roinntear é faoi -13 cuirtear an iolrúchán faoi -13 ar ceal.

$$n=\frac{-m^{2}-72}{-13}$$

Roinn -m^{2}-72 faoi -13.

$$n=\frac{m^{2}+72}{13}$$

Réitigh do m. (complex solution)

$$m=-\sqrt{13n-72}$$

$$m=\sqrt{13n-72}$$

Réitigh do m.

$$m=\sqrt{13n-72}$$

$$m=-\sqrt{13n-72}\text{, }n\geq \frac{72}{13}$$
