DC_{4}+x^{2}=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
DC_{4}=A-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
\frac{DC_{4}}{D}=\frac{A-x^{2}}{D}
Whakawehea ngā taha e rua ki te D.
C_{4}=\frac{A-x^{2}}{D}
Mā te whakawehe ki te D ka wetekia te whakareanga ki te D.
