36+x^{2}=x^{2}+4.8x+5.76
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+2.4\right)^{2}.
36+x^{2}-x^{2}=4.8x+5.76
Tangohia te x^{2} mai i ngā taha e rua.
36=4.8x+5.76
Pahekotia te x^{2} me -x^{2}, ka 0.
4.8x+5.76=36
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4.8x=36-5.76
Tangohia te 5.76 mai i ngā taha e rua.
4.8x=30.24
Tangohia te 5.76 i te 36, ka 30.24.
x=\frac{30.24}{4.8}
Whakawehea ngā taha e rua ki te 4.8.
x=\frac{3024}{480}
Whakarohaina te \frac{30.24}{4.8} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{63}{10}
Whakahekea te hautanga \frac{3024}{480} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 48.
