Ngā Upane Otinga

Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(3\sqrt{2}-2\sqrt{3}\right)^{2}.

$$9\left(\sqrt{2}\right)^{2}-12\sqrt{2}\sqrt{3}+4\left(\sqrt{3}\right)^{2}$$

Ko te pūrua o \sqrt{2} ko 2.

$$9\times 2-12\sqrt{2}\sqrt{3}+4\left(\sqrt{3}\right)^{2}$$

Whakareatia te 9 ki te 2, ka 18.

$$18-12\sqrt{2}\sqrt{3}+4\left(\sqrt{3}\right)^{2}$$

Hei whakarea \sqrt{2} me \sqrt{3}, whakareatia ngā tau i raro i te pūtake rua.

$$18-12\sqrt{6}+4\left(\sqrt{3}\right)^{2}$$

Ko te pūrua o \sqrt{3} ko 3.

$$18-12\sqrt{6}+4\times 3$$

Whakareatia te 4 ki te 3, ka 12.

$$18-12\sqrt{6}+12$$

Tāpirihia te 18 ki te 12, ka 30.

$$30-12\sqrt{6}$$
