Roinn
Cóipeáladh go dtí an ghearrthaisce
x-75-\left(-75\right)=15\sqrt{21}i-\left(-75\right) x-75-\left(-75\right)=-15\sqrt{21}i-\left(-75\right)
Cuir 75 leis an dá thaobh den chothromóid.
x=15\sqrt{21}i-\left(-75\right) x=-15\sqrt{21}i-\left(-75\right)
Má dhealaítear -75 uaidh féin faightear 0.
x=75+15\sqrt{21}i
Dealaigh -75 ó 15i\sqrt{21}.
x=-15\sqrt{21}i+75
Dealaigh -75 ó -15i\sqrt{21}.
x=75+15\sqrt{21}i x=-15\sqrt{21}i+75
Tá an chothromóid réitithe anois.
