Kua tāruatia ki te papatopenga
\left(-x^{2}\right)^{2}+6\left(-x^{2}\right)+9
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(-x^{2}+3\right)^{2}.
\left(x^{2}\right)^{2}+6\left(-x^{2}\right)+9
Tātaihia te -x^{2} mā te pū o 2, kia riro ko \left(x^{2}\right)^{2}.
x^{4}+6\left(-x^{2}\right)+9
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}-6x^{2}+9
Whakareatia te 6 ki te -1, ka -6.
