Lahenda 2sqrt{2}C=c^2-16

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

Lahendage ja leidke C

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

Juhised lineaarvõrrandi lahendamiseks

Võrrand on standardkujul.

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

Jagage mõlemad pooled 2\sqrt{2}-ga.

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

2\sqrt{2}-ga jagamine võtab 2\sqrt{2}-ga korrutamise tagasi.

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

Jagage c^{2}-16 väärtusega 2\sqrt{2}.

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

Lahendage ja leidke c (complex solution)

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

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

Lahendage ja leidke c

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

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