Kua tāruatia ki te papatopenga
3x^{2}+14x-5=3x^{2}
Whakamahia te āhuatanga tuaritanga hei whakarea te 3x-1 ki te x+5 ka whakakotahi i ngā kupu rite.
3x^{2}+14x-5-3x^{2}=0
Tangohia te 3x^{2} mai i ngā taha e rua.
14x-5=0
Pahekotia te 3x^{2} me -3x^{2}, ka 0.
14x=5
Me tāpiri te 5 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{5}{14}
Whakawehea ngā taha e rua ki te 14.
