Whakaoti i te {l}{(-2x)^2-(-3x)}{-x^2*(-3x)^2-3x^2}

$$\left. \begin{array} { l } { ( - 2 x ) ^ { 2 } - ( - 3 x ) } \\ { - x ^ { 2 } \times ( - 3 x ) ^ { 2 } - 3 x ^ { 2 } } \end{array} \right.$$

Ngā Upane Otinga

Whakarohaina te \left(-2x\right)^{2}.

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

Tātaihia te -2 mā te pū o 2, kia riro ko 4.

$$4x^{2}-\left(-3x\right)-x^{2}\left(-3x\right)^{2}-3x^{2}$$

Ko te tauaro o -3x ko 3x.

$$4x^{2}+3x-x^{2}\left(-3x\right)^{2}-3x^{2}$$

Whakarohaina te \left(-3x\right)^{2}.

$$4x^{2}+3x-x^{2}\left(-3\right)^{2}x^{2}-3x^{2}$$

Tātaihia te -3 mā te pū o 2, kia riro ko 9.

$$4x^{2}+3x-x^{2}\times 9x^{2}-3x^{2}$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 2 kia riro ai te 4.

$$4x^{2}+3x-x^{4}\times 9-3x^{2}$$

Whakareatia te -1 ki te 9, ka -9.

$$4x^{2}+3x-9x^{4}-3x^{2}$$

Pahekotia te 4x^{2} me -3x^{2}, ka x^{2}.

$$x^{2}+3x-9x^{4}$$

Whakaroha
