Whakaoti i te (x+5)(x-4x-3i)(x-4x+3i)

$$( x + 5 ) ( x - 4 x - 3 i ) ( x - 4 x + 3 i )$$

Aromātai

$$-9\left(x+5\right)\left(-x^{2}-1\right)$$

Ngā Upane Otinga

Pahekotia te x me -4x, ka -3x.

$$\left(x+5\right)\left(-3x-3i\right)\left(x-4x+3i\right)$$

Pahekotia te x me -4x, ka -3x.

$$\left(x+5\right)\left(-3x-3i\right)\left(-3x+3i\right)$$

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x+5 ki ia tau o -3x-3i.

$$\left(-3x^{2}-3ix-15x-15i\right)\left(-3x+3i\right)$$

Pahekotia te -3ix me -15x, ka \left(-15-3i\right)x.

$$\left(-3x^{2}+\left(-15-3i\right)x-15i\right)\left(-3x+3i\right)$$

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o -3x^{2}+\left(-15-3i\right)x-15i ki ia tau o -3x+3i.

$$9x^{3}-9ix^{2}+\left(45+9i\right)x^{2}+\left(9-45i\right)x+45ix+45$$

Pahekotia te -9ix^{2} me \left(45+9i\right)x^{2}, ka 45x^{2}.

$$9x^{3}+45x^{2}+\left(9-45i\right)x+45ix+45$$

Pahekotia te \left(9-45i\right)x me 45ix, ka 9x.

$$9x^{3}+45x^{2}+9x+45$$

Whakaroha

$$9x^{3}+45x^{2}+9x+45$$
