Kua tāruatia ki te papatopenga
y=0\left(x-30\right)^{2}+12
Whakareatia te 0 ki te 2, ka 0.
y=0\left(x^{2}-60x+900\right)+12
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-30\right)^{2}.
y=0+12
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=12
Tāpirihia te 0 ki te 12, ka 12.
