Kua tāruatia ki te papatopenga
x^{2}-\left(x^{2}-2x\right)-\left(x+6\right)=0
Whakamahia te āhuatanga tohatoha hei whakarea te x-2 ki te x.
x^{2}-x^{2}+2x-\left(x+6\right)=0
Hei kimi i te tauaro o x^{2}-2x, kimihia te tauaro o ia taurangi.
2x-\left(x+6\right)=0
Pahekotia te x^{2} me -x^{2}, ka 0.
2x-x-6=0
Hei kimi i te tauaro o x+6, kimihia te tauaro o ia taurangi.
x-6=0
Pahekotia te 2x me -x, ka x.
x=6
Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
