Tohaina
Kua tāruatia ki te papatopenga
y=\frac{-x^{2}}{-x^{2}}
Tātaihia te \sqrt{-x^{2}} mā te pū o 2, kia riro ko -x^{2}.
y=-\frac{x^{2}}{-x^{2}}
Whakaraupapatia anō ngā kīanga tau.
y=-\frac{1}{-1}
Me whakakore tahi te x^{2} i te taurunga me te tauraro.
y=-\left(-1\right)
Whakawehea te 1 ki te -1, kia riro ko -1.
y=1
Whakareatia te -1 ki te -1, ka 1.
