Réitigh sqrt{2}x+2(sqrt{2}+2)=sqrt{2}

$$\sqrt { 2 } x + 2 ( \sqrt { 2 } + 2 ) = \sqrt { 2 }$$

Réitigh do x.

$$x=-2\sqrt{2}-1\approx -3.828427125$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Úsáid an t-airí dáileach chun 2 a mhéadú faoi \sqrt{2}+2.

$$\sqrt{2}x+2\sqrt{2}+4=\sqrt{2}$$

Bain 2\sqrt{2} ón dá thaobh.

$$\sqrt{2}x+4=\sqrt{2}-2\sqrt{2}$$

Comhcheangail \sqrt{2} agus -2\sqrt{2} chun -\sqrt{2} a fháil.

$$\sqrt{2}x+4=-\sqrt{2}$$

Bain 4 ón dá thaobh.

$$\sqrt{2}x=-\sqrt{2}-4$$

Roinn an dá thaobh faoi \sqrt{2}.

$$\frac{\sqrt{2}x}{\sqrt{2}}=\frac{-\sqrt{2}-4}{\sqrt{2}}$$

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

$$x=\frac{-\sqrt{2}-4}{\sqrt{2}}$$

Roinn -\sqrt{2}-4 faoi \sqrt{2}.

$$x=-2\sqrt{2}-1$$
