Whakaoti i te (a+ib-5)(a-ib-5

$$( a + i b - 5 ) ( a - i b - 5$$

Aromātai

$$\left(a-5\right)^{2}+b^{2}$$

Ngā Upane Otinga

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o a+ib-5 ki ia tau o a-ib-5.

$$a\left(a-ib\right)-5a+ib\left(a-ib\right)-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te a-ib.

$$a^{2}-iab-5a+ib\left(a-ib\right)-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te ib ki te a-ib.

$$a^{2}-iab-5a+iba+b^{2}-5ib-5\left(a-ib\right)+25$$

Pahekotia te -iab me iba, ka 0.

$$a^{2}-5a+b^{2}-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te a-ib.

$$a^{2}-5a+b^{2}-5ib-5a+5ib+25$$

Pahekotia te -5a me -5a, ka -10a.

$$a^{2}-10a+b^{2}-5ib+5ib+25$$

Pahekotia te -5ib me 5ib, ka 0.

$$a^{2}-10a+b^{2}+25$$

Whakaroha

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o a+ib-5 ki ia tau o a-ib-5.

$$a\left(a-ib\right)-5a+ib\left(a-ib\right)-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te a-ib.

$$a^{2}-iab-5a+ib\left(a-ib\right)-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te ib ki te a-ib.

$$a^{2}-iab-5a+iba+b^{2}-5ib-5\left(a-ib\right)+25$$

Pahekotia te -iab me iba, ka 0.

$$a^{2}-5a+b^{2}-5ib-5\left(a-ib\right)+25$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te a-ib.

$$a^{2}-5a+b^{2}-5ib-5a+5ib+25$$

Pahekotia te -5a me -5a, ka -10a.

$$a^{2}-10a+b^{2}-5ib+5ib+25$$

Pahekotia te -5ib me 5ib, ka 0.

$$a^{2}-10a+b^{2}+25$$
