Réitigh 5(g+8)^2+12=1727

$$5 ( g + 8 ) ^ { 2 } + 12 = 1727$$

Réitigh do g.

$$g=7\sqrt{7}-8\approx 10.520259177$$

$$g=-7\sqrt{7}-8\approx -26.520259177$$

Céimeanna tríd an bhFréamh Chearnach a Fháil

Bain 12 ón dá thaobh den chothromóid.

$$5\left(g+8\right)^{2}+12-12=1727-12$$

Má dhealaítear 12 uaidh féin faightear 0.

$$5\left(g+8\right)^{2}=1727-12$$

Dealaigh 12 ó 1727.

$$5\left(g+8\right)^{2}=1715$$

Roinn an dá thaobh faoi 5.

$$\frac{5\left(g+8\right)^{2}}{5}=\frac{1715}{5}$$

Má roinntear é faoi 5 cuirtear an iolrúchán faoi 5 ar ceal.

$$\left(g+8\right)^{2}=\frac{1715}{5}$$

Roinn 1715 faoi 5.

$$\left(g+8\right)^{2}=343$$

Tóg fréamh chearnach an dá thaobh den chothromóid.

$$g+8=7\sqrt{7} g+8=-7\sqrt{7}$$

Bain 8 ón dá thaobh den chothromóid.

$$g+8-8=7\sqrt{7}-8 g+8-8=-7\sqrt{7}-8$$

Má dhealaítear 8 uaidh féin faightear 0.

$$g=7\sqrt{7}-8 g=-7\sqrt{7}-8$$
