Kua tāruatia ki te papatopenga
3x^{2}+x-2=3x^{2}-5
Whakamahia te āhuatanga tuaritanga hei whakarea te 3x-2 ki te x+1 ka whakakotahi i ngā kupu rite.
3x^{2}+x-2-3x^{2}=-5
Tangohia te 3x^{2} mai i ngā taha e rua.
x-2=-5
Pahekotia te 3x^{2} me -3x^{2}, ka 0.
x=-5+2
Me tāpiri te 2 ki ngā taha e rua.
x=-3
Tāpirihia te -5 ki te 2, ka -3.
