ax^{2}+7x=D
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
ax^{2}=D-7x
Tangohia te 7x mai i ngā taha e rua.
x^{2}a=D-7x
He hanga arowhānui tō te whārite.
\frac{x^{2}a}{x^{2}}=\frac{D-7x}{x^{2}}
Whakawehea ngā taha e rua ki te x^{2}.
a=\frac{D-7x}{x^{2}}
Mā te whakawehe ki te x^{2} ka wetekia te whakareanga ki te x^{2}.
