Kua tāruatia ki te papatopenga
-7\left(x^{2}-8x+16\right)+4
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-4\right)^{2}.
-7x^{2}+56x-112+4
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x^{2}-8x+16.
-7x^{2}+56x-108
Tāpirihia te -112 ki te 4, ka -108.
-7\left(x^{2}-8x+16\right)+4
