Whakaoti i te 25(x+2)^2-36=0

$$25 ( x + 2 ) ^ { 2 } - 36 = 0$$

Whakaoti mō x

$$x=-\frac{4}{5}=-0.8$$

$$x = -\frac{16}{5} = -3\frac{1}{5} = -3.2$$

Ngā Upane mā te Kimi Pūtakerua

Me tāpiri 36 ki ngā taha e rua o te whārite.

$$25\left(x+2\right)^{2}-36+36=36$$

Mā te tango i te 36 i a ia ake anō ka toe ko te 0.

$$25\left(x+2\right)^{2}=36$$

Whakawehea ngā taha e rua ki te 25.

$$\frac{25\left(x+2\right)^{2}}{25}=\frac{36}{25}$$

Mā te whakawehe ki te 25 ka wetekia te whakareanga ki te 25.

$$\left(x+2\right)^{2}=\frac{36}{25}$$

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$x+2=\frac{6}{5} x+2=-\frac{6}{5}$$

Me tango 2 mai i ngā taha e rua o te whārite.

$$x+2-2=\frac{6}{5}-2 x+2-2=-\frac{6}{5}-2$$

Mā te tango i te 2 i a ia ake anō ka toe ko te 0.

$$x=\frac{6}{5}-2 x=-\frac{6}{5}-2$$

Tango 2 mai i \frac{6}{5}.

$$x=-\frac{4}{5}$$

Tango 2 mai i -\frac{6}{5}.

$$x=-\frac{16}{5}$$

Kua oti te whārite te whakatau.

$$x=-\frac{4}{5} x=-\frac{16}{5}$$
