Kua tāruatia ki te papatopenga
\left(x-2\right)\times 3+x+1=0
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -1,2 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-2\right)\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+1,x-2.
3x-6+x+1=0
Whakamahia te āhuatanga tohatoha hei whakarea te x-2 ki te 3.
4x-6+1=0
Pahekotia te 3x me x, ka 4x.
4x-5=0
Tāpirihia te -6 ki te 1, ka -5.
4x=5
Me tāpiri te 5 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{5}{4}
Whakawehea ngā taha e rua ki te 4.
