Whakaoti i te -0007x^2+13x^2+04225=0

$$-0007 { x }^{ 2 } +13 { x }^{ 2 } +04225=0$$

Whakaoti mō x

$$x=0$$

Ngā Upane mā te Kimi Pūtakerua

Mahia ngā whakarea.

$$0\times 0\times 7x^{2}+13x^{2}+0=0$$

Whakareatia te 0 ki te 0, ka 0.

$$0\times 7x^{2}+13x^{2}+0=0$$

Whakareatia te 0 ki te 7, ka 0.

$$0x^{2}+13x^{2}+0=0$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0+13x^{2}+0=0$$

Tāpirihia te 0 ki te 0, ka 0.

$$13x^{2}=0$$

Whakawehea ngā taha e rua ki te 13. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$x^{2}=0$$

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

$$x=0 x=0$$

Kua oti te whārite te whakatau. He ōrite ngā whakatau.

$$x=0$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Mahia ngā whakarea.

$$0\times 0\times 7x^{2}+13x^{2}+0=0$$

Whakareatia te 0 ki te 0, ka 0.

$$0\times 7x^{2}+13x^{2}+0=0$$

Whakareatia te 0 ki te 7, ka 0.

$$0x^{2}+13x^{2}+0=0$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0+13x^{2}+0=0$$

Tāpirihia te 0 ki te 0, ka 0.

$$13x^{2}=0$$

Whakawehea ngā taha e rua ki te 13. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$x^{2}=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 0 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}}}{2}$$

Tuhia te pūtakerua o te 0^{2}.

$$x=\frac{0±0}{2}$$

Whakawehe 0 ki te 2.

$$x=0$$
