Réitigh alphabeta^2=4

$$\alpha \beta ^ { 2 } = 4$$

Réitigh do α.

$$\alpha =\frac{4}{\beta ^{2}}$$

$$\beta \neq 0$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Tá an chothromóid i bhfoirm chaighdeánach.

$$\beta ^{2}\alpha =4$$

Roinn an dá thaobh faoi \beta ^{2}.

$$\frac{\beta ^{2}\alpha }{\beta ^{2}}=\frac{4}{\beta ^{2}}$$

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

$$\alpha =\frac{4}{\beta ^{2}}$$

Réitigh do β.

$$\beta =\frac{2}{\sqrt{\alpha }}$$

$$\beta =-\frac{2}{\sqrt{\alpha }}\text{, }\alpha >0$$
