Kua tāruatia ki te papatopenga
1-a^{2}+aa+a\left(-3\right)=11a
Tē taea kia ōrite te tāupe a ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te a.
1-a^{2}+a^{2}+a\left(-3\right)=11a
Whakareatia te a ki te a, ka a^{2}.
1+a\left(-3\right)=11a
Pahekotia te -a^{2} me a^{2}, ka 0.
1+a\left(-3\right)-11a=0
Tangohia te 11a mai i ngā taha e rua.
1-14a=0
Pahekotia te a\left(-3\right) me -11a, ka -14a.
-14a=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
a=\frac{-1}{-14}
Whakawehea ngā taha e rua ki te -14.
a=\frac{1}{14}
Ka taea te hautanga \frac{-1}{-14} te whakamāmā ki te \frac{1}{14} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
