(-3+5i)(-6+6i) eching

$$( - 3 + 5 i ) ( - 6 + 6 i )$$

Baholash

$$-12-48i$$

Yechim qadamlari

Binomlarni ko‘paytirgandek -3+5i va -6+6i murakkab sonlarni ko‘paytiring.

$$-3\left(-6\right)-3\times \left(6i\right)+5i\left(-6\right)+5\times 6i^{2}$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$-3\left(-6\right)-3\times \left(6i\right)+5i\left(-6\right)+5\times 6\left(-1\right)$$

Ko‘paytirishlarni bajaring.

$$18-18i-30i-30$$

Real va mavhum qismlarni birlashtiring.

$$18-30+\left(-18-30\right)i$$

Qo‘shishlarni bajaring.

$$-12-48i$$

Ashyoviy qism

$$-12$$

Yechim qadamlari

Binomlarni ko‘paytirgandek -3+5i va -6+6i murakkab sonlarni ko‘paytiring.

$$Re(-3\left(-6\right)-3\times \left(6i\right)+5i\left(-6\right)+5\times 6i^{2})$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$Re(-3\left(-6\right)-3\times \left(6i\right)+5i\left(-6\right)+5\times 6\left(-1\right))$$

-3\left(-6\right)-3\times \left(6i\right)+5i\left(-6\right)+5\times 6\left(-1\right) ichidagi ko‘paytirishlarni bajaring.

$$Re(18-18i-30i-30)$$

18-18i-30i-30 ichida real va mavhum qismlarni birlashtiring.

$$Re(18-30+\left(-18-30\right)i)$$

18-30+\left(-18-30\right)i ichida qo‘shishlarni bajaring.

$$Re(-12-48i)$$

-12-48i ning real qismi – -12.

$$-12$$
