5 fadhbanna cosúil le:
( x - 2 ) ^ { 2 } = 22
Roinn
Cóipeáladh go dtí an ghearrthaisce
x-2=\sqrt{22} x-2=-\sqrt{22}
Tóg fréamh chearnach an dá thaobh den chothromóid.
x-2-\left(-2\right)=\sqrt{22}-\left(-2\right) x-2-\left(-2\right)=-\sqrt{22}-\left(-2\right)
Cuir 2 leis an dá thaobh den chothromóid.
x=\sqrt{22}-\left(-2\right) x=-\sqrt{22}-\left(-2\right)
Má dhealaítear -2 uaidh féin faightear 0.
x=\sqrt{22}+2
Dealaigh -2 ó \sqrt{22}.
x=2-\sqrt{22}
Dealaigh -2 ó -\sqrt{22}.
x=\sqrt{22}+2 x=2-\sqrt{22}
Tá an chothromóid réitithe anois.
