Kua tāruatia ki te papatopenga
\sqrt{x}+9-9=11-9
Me tango 9 mai i ngā taha e rua o te whārite.
\sqrt{x}=11-9
Mā te tango i te 9 i a ia ake anō ka toe ko te 0.
\sqrt{x}=2
Tango 9 mai i 11.
x=4
Pūruatia ngā taha e rua o te whārite.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
