Tohaina
Kua tāruatia ki te papatopenga
-2a\left(a^{2}-22a+121\right)
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(a-11\right)^{2}.
-2a^{3}+44a^{2}-242a
Whakamahia te āhuatanga tohatoha hei whakarea te -2a ki te a^{2}-22a+121.
-2a\left(a^{2}-22a+121\right)
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(a-11\right)^{2}.
-2a^{3}+44a^{2}-242a
Whakamahia te āhuatanga tohatoha hei whakarea te -2a ki te a^{2}-22a+121.
