Kua tāruatia ki te papatopenga
x^{2}-2a=1+\sqrt{x+1}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2a=1+\sqrt{x+1}-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
-2a=-x^{2}+\sqrt{x+1}+1
He hanga arowhānui tō te whārite.
\frac{-2a}{-2}=\frac{-x^{2}+\sqrt{x+1}+1}{-2}
Whakawehea ngā taha e rua ki te -2.
a=\frac{-x^{2}+\sqrt{x+1}+1}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
a=\frac{x^{2}-\sqrt{x+1}-1}{2}
Whakawehe 1+\sqrt{x+1}-x^{2} ki te -2.
