Réitigh 2sqrt{2}C=c^2-16

$$2 \sqrt { 2 } C = c ^ { 2 } - 16$$

Réitigh do C.

$$C=-\frac{\sqrt{2}\left(16-c^{2}\right)}{4}$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Tá an chothromóid i bhfoirm chaighdeánach.

$$2\sqrt{2}C=c^{2}-16$$

Roinn an dá thaobh faoi 2\sqrt{2}.

$$\frac{2\sqrt{2}C}{2\sqrt{2}}=\frac{c^{2}-16}{2\sqrt{2}}$$

Má roinntear é faoi 2\sqrt{2} cuirtear an iolrúchán faoi 2\sqrt{2} ar ceal.

$$C=\frac{c^{2}-16}{2\sqrt{2}}$$

Roinn c^{2}-16 faoi 2\sqrt{2}.

$$C=\frac{\sqrt{2}\left(c^{2}-16\right)}{4}$$

Réitigh do c. (complex solution)

$$c=-\sqrt{2\sqrt{2}C+16}$$

$$c=\sqrt{2\sqrt{2}C+16}$$

Réitigh do c.

$$c=\sqrt{2\sqrt{2}C+16}$$

$$c=-\sqrt{2\sqrt{2}C+16}\text{, }C\geq -4\sqrt{2}$$
