Whakaoti mō y
y=-\left(x-2\right)^{2}
Whakaoti mō x (complex solution)
x=-i\sqrt{y}+2
x=i\sqrt{y}+2
Whakaoti mō x
x=-\sqrt{-y}+2
x=\sqrt{-y}+2\text{, }y\leq 0

Kua tāruatia ki te papatopenga
y=-\left(x^{2}-4x+4\right)
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-2\right)^{2}.
y=-x^{2}+4x-4
Hei kimi i te tauaro o x^{2}-4x+4, kimihia te tauaro o ia taurangi.
