Céimeanna chun Cothromóidí Líneacha a Réiteach

Iolraigh an dá thaobh den chothromóid faoi 70m^{2}, an comhiolraí is lú de mm,5,14.

$$70Cup\times \frac{1}{5}=5m^{2}\times 274$$

Méadaigh 70 agus \frac{1}{5} chun 14 a fháil.

$$14Cup=5m^{2}\times 274$$

Méadaigh 5 agus 274 chun 1370 a fháil.

$$14Cup=1370m^{2}$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$14puC=1370m^{2}$$

Roinn an dá thaobh faoi 14up.

$$\frac{14puC}{14pu}=\frac{1370m^{2}}{14pu}$$

Má roinntear é faoi 14up cuirtear an iolrúchán faoi 14up ar ceal.

$$C=\frac{1370m^{2}}{14pu}$$

Roinn 1370m^{2} faoi 14up.

$$C=\frac{685m^{2}}{7pu}$$

Réitigh do m. (complex solution)

$$m=-\frac{\sqrt{C}\sqrt{u}\sqrt{4795p}}{685}$$

$$m=\frac{\sqrt{C}\sqrt{u}\sqrt{4795p}}{685}\text{, }p\neq 0\text{ and }u\neq 0\text{ and }C\neq 0$$

Réitigh do m.

$$m=\frac{\sqrt{4795Cpu}}{685}$$

$$m=-\frac{\sqrt{4795Cpu}}{685}\text{, }\left(C<0\text{ and }p<0\text{ and }u>0\right)\text{ or }\left(p>0\text{ and }C>0\text{ and }u>0\right)\text{ or }\left(u<0\text{ and }p<0\text{ and }C>0\right)\text{ or }\left(u<0\text{ and }C<0\text{ and }p>0\right)$$
