Kua tāruatia ki te papatopenga
2+4i\left(-3\right)+4\left(-1\right)i^{2}
Whakareatia 4i ki te -3-i.
2+4i\left(-3\right)+4\left(-1\right)\left(-1\right)
Hei tōna tikanga, ko te i^{2} ko -1.
2+\left(4-12i\right)
Mahia ngā whakarea i roto o 4i\left(-3\right)+4\left(-1\right)\left(-1\right). Whakaraupapatia anō ngā kīanga tau.
2+4-12i
Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa.
6-12i
Tāpiri 2 ki te 4.
Re(2+4i\left(-3\right)+4\left(-1\right)i^{2})
Whakareatia 4i ki te -3-i.
Re(2+4i\left(-3\right)+4\left(-1\right)\left(-1\right))
Hei tōna tikanga, ko te i^{2} ko -1.
Re(2+\left(4-12i\right))
Mahia ngā whakarea i roto o 4i\left(-3\right)+4\left(-1\right)\left(-1\right). Whakaraupapatia anō ngā kīanga tau.
Re(2+4-12i)
Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa ki 2+4-12i.
Re(6-12i)
Tāpiri 2 ki te 4.
