Kua tāruatia ki te papatopenga
x-\frac{\left(x-3\right)^{2}}{2^{2}}
Kia whakarewa i te \frac{x-3}{2} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.
x-\frac{\left(x-3\right)^{2}}{4}
Tātaihia te 2 mā te pū o 2, kia riro ko 4.
\frac{4x}{4}-\frac{\left(x-3\right)^{2}}{4}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia x ki te \frac{4}{4}.
\frac{4x-\left(x-3\right)^{2}}{4}
Tā te mea he rite te tauraro o \frac{4x}{4} me \frac{\left(x-3\right)^{2}}{4}, me tango rāua mā te tango i ō raua taurunga.
\frac{4x-x^{2}+6x-9}{4}
Mahia ngā whakarea i roto o 4x-\left(x-3\right)^{2}.
\frac{10x-x^{2}-9}{4}
Whakakotahitia ngā kupu rite i 4x-x^{2}+6x-9.
x-\frac{\left(x-3\right)^{2}}{2^{2}}
Kia whakarewa i te \frac{x-3}{2} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

\frac{4x}{4}-\frac{\left(x-3\right)^{2}}{4}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia x ki te \frac{4}{4}.
\frac{4x-\left(x-3\right)^{2}}{4}
Tā te mea he rite te tauraro o \frac{4x}{4} me \frac{\left(x-3\right)^{2}}{4}, me tango rāua mā te tango i ō raua taurunga.
\frac{4x-x^{2}+6x-9}{4}
Mahia ngā whakarea i roto o 4x-\left(x-3\right)^{2}.
\frac{10x-x^{2}-9}{4}
Whakakotahitia ngā kupu rite i 4x-x^{2}+6x-9.
