Réitigh y^2=u^2+2as

$$y ^ { 2 } = u ^ { 2 } + 2 a s$$

Réitigh do a.

$$\left\{\begin{matrix}a=-\frac{u^{2}-y^{2}}{2s}\text{, }&s\neq 0\\a\in \mathrm{R}\text{, }&s=0\text{ and }|y|=|u|\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$u^{2}+2as=y^{2}$$

Bain u^{2} ón dá thaobh.

$$2as=y^{2}-u^{2}$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$2sa=y^{2}-u^{2}$$

Roinn an dá thaobh faoi 2s.

$$\frac{2sa}{2s}=\frac{\left(y-u\right)\left(y+u\right)}{2s}$$

Má roinntear é faoi 2s cuirtear an iolrúchán faoi 2s ar ceal.

$$a=\frac{\left(y-u\right)\left(y+u\right)}{2s}$$

Réitigh do s.

$$\left\{\begin{matrix}s=-\frac{u^{2}-y^{2}}{2a}\text{, }&a\neq 0\\s\in \mathrm{R}\text{, }&a=0\text{ and }|y|=|u|\end{matrix}\right.$$

$$u^{2}+2as=y^{2}$$

Bain u^{2} ón dá thaobh.

$$2as=y^{2}-u^{2}$$

Roinn an dá thaobh faoi 2a.

$$\frac{2as}{2a}=\frac{\left(y-u\right)\left(y+u\right)}{2a}$$

Má roinntear é faoi 2a cuirtear an iolrúchán faoi 2a ar ceal.

$$s=\frac{\left(y-u\right)\left(y+u\right)}{2a}$$
