$$( 2 i ) ( - 8 - i ) + 3 ( - 3 - i )$$

Aromātai

$$-7-19i$$

Ngā Upane Otinga

Whakareatia 2i ki te -8-i.

$$2i\left(-8\right)+2\left(-1\right)i^{2}+3\left(-3-i\right)$$

Hei tōna tikanga, ko te i^{2} ko -1.

$$2i\left(-8\right)+2\left(-1\right)\left(-1\right)+3\left(-3-i\right)$$

Mahia ngā whakarea i roto o 2i\left(-8\right)+2\left(-1\right)\left(-1\right). Whakaraupapatia anō ngā kīanga tau.

$$2-16i+3\left(-3-i\right)$$

Whakareatia 3 ki te -3-i.

$$2-16i+3\left(-3\right)+3\left(-i\right)$$

Mahia ngā whakarea i roto o 3\left(-3\right)+3\left(-i\right).

$$2-16i+\left(-9-3i\right)$$

Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa.

$$2-9+\left(-16-3\right)i$$

Mahia ngā tāpiri.

$$-7-19i$$
