Kua tāruatia ki te papatopenga
\left(x+7\right)^{2}-11+11=11
Me tāpiri 11 ki ngā taha e rua o te whārite.
\left(x+7\right)^{2}=11
Mā te tango i te 11 i a ia ake anō ka toe ko te 0.
x+7=\sqrt{11} x+7=-\sqrt{11}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x+7-7=\sqrt{11}-7 x+7-7=-\sqrt{11}-7
Me tango 7 mai i ngā taha e rua o te whārite.
x=\sqrt{11}-7 x=-\sqrt{11}-7
Mā te tango i te 7 i a ia ake anō ka toe ko te 0.
