Kua tāruatia ki te papatopenga
\sqrt{x}+2-2=7-2
Me tango 2 mai i ngā taha e rua o te whārite.
\sqrt{x}=7-2
Mā te tango i te 2 i a ia ake anō ka toe ko te 0.
\sqrt{x}=5
Tango 2 mai i 7.
x=25
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
Arithmetic
