Tohaina
Kua tāruatia ki te papatopenga
\left(-b\right)^{2}-14\left(-b\right)+49
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(-b-7\right)^{2}.
b^{2}-14\left(-b\right)+49
Tātaihia te -b mā te pū o 2, kia riro ko b^{2}.
b^{2}+14b+49
Whakareatia te -14 ki te -1, ka 14.
\left(-b\right)^{2}-14\left(-b\right)+49
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(-b-7\right)^{2}.
b^{2}-14\left(-b\right)+49
Tātaihia te -b mā te pū o 2, kia riro ko b^{2}.
b^{2}+14b+49
Whakareatia te -14 ki te -1, ka 14.
