Whakaoti i te (2-i)(3+2i)

$$( 2 - i ) ( 3 + 2 i )$$

Aromātai

$$8+i$$

Ngā Upane Otinga

Me whakarea ngā tau matatini 2-i me 3+2i pēnā i te whakarea huarua.

$$2\times 3+2\times \left(2i\right)-i\times 3-2i^{2}$$

Hei tōna tikanga, ko te i^{2} ko -1.

$$2\times 3+2\times \left(2i\right)-i\times 3-2\left(-1\right)$$

Mahia ngā whakarea.

$$6+4i-3i+2$$

Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa.

$$6+2+\left(4-3\right)i$$

Mahia ngā tāpiri.

$$8+i$$
