u^{2}-2gh=v^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2gh=v^{2}-u^{2}
Tangohia te u^{2} mai i ngā taha e rua.
\left(-2h\right)g=v^{2}-u^{2}
He hanga arowhānui tō te whārite.
\frac{\left(-2h\right)g}{-2h}=\frac{\left(v-u\right)\left(u+v\right)}{-2h}
Whakawehea ngā taha e rua ki te -2h.
g=\frac{\left(v-u\right)\left(u+v\right)}{-2h}
Mā te whakawehe ki te -2h ka wetekia te whakareanga ki te -2h.
g=-\frac{\left(v-u\right)\left(u+v\right)}{2h}
Whakawehe \left(v+u\right)\left(v-u\right) ki te -2h.
u^{2}-2gh=v^{2}

Mā te whakawehe ki te -2g ka wetekia te whakareanga ki te -2g.
h=-\frac{\left(v-u\right)\left(u+v\right)}{2g}
Whakawehe \left(v+u\right)\left(v-u\right) ki te -2g.
