Kua tāruatia ki te papatopenga
\left(x^{2}\right)^{2}-4x^{2}+4-4
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x^{2}-2\right)^{2}.
x^{4}-4x^{2}+4-4
Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 2 me te 2 kia riro ai te 4.
x^{4}-4x^{2}
Tangohia te 4 i te 4, ka 0.
\left(x^{2}\right)^{2}-4x^{2}+4-4
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x^{2}-2\right)^{2}.
x^{4}-4x^{2}+4-4
Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 2 me te 2 kia riro ai te 4.
