Réitigh -left(0-1+mright)^2+2=-1

$$- { \left(0-1+m \right) }^{ 2 } +2 = -1$$

Réitigh do m.

$$m=\sqrt{3}+1\approx 2.732050808$$

$$m=1-\sqrt{3}\approx -0.732050808$$

Céimeanna tríd an bhFréamh Chearnach a Fháil

Bain 2 ón dá thaobh den chothromóid.

$$-\left(m-1\right)^{2}+2-2=-1-2$$

Má dhealaítear 2 uaidh féin faightear 0.

$$-\left(m-1\right)^{2}=-1-2$$

Dealaigh 2 ó -1.

$$-\left(m-1\right)^{2}=-3$$

Roinn an dá thaobh faoi -1.

$$\frac{-\left(m-1\right)^{2}}{-1}=-\frac{3}{-1}$$

Má roinntear é faoi -1 cuirtear an iolrúchán faoi -1 ar ceal.

$$\left(m-1\right)^{2}=-\frac{3}{-1}$$

Roinn -3 faoi -1.

$$\left(m-1\right)^{2}=3$$

Tóg fréamh chearnach an dá thaobh den chothromóid.

$$m-1=\sqrt{3} m-1=-\sqrt{3}$$

Cuir 1 leis an dá thaobh den chothromóid.

$$m-1-\left(-1\right)=\sqrt{3}-\left(-1\right) m-1-\left(-1\right)=-\sqrt{3}-\left(-1\right)$$

Má dhealaítear -1 uaidh féin faightear 0.

$$m=\sqrt{3}-\left(-1\right) m=-\sqrt{3}-\left(-1\right)$$

Dealaigh -1 ó \sqrt{3}.

$$m=\sqrt{3}+1$$

Dealaigh -1 ó -\sqrt{3}.

$$m=1-\sqrt{3}$$

Tá an chothromóid réitithe anois.

$$m=\sqrt{3}+1 m=1-\sqrt{3}$$
