Tohaina
Kua tāruatia ki te papatopenga
m-5=2
Tē taea kia ōrite te tāupe m ki tētahi o ngā uara -5,5 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(m-5\right)\left(m+5\right), arā, te tauraro pātahi he tino iti rawa te kitea o m+5,m^{2}-25.
m=2+5
Me tāpiri te 5 ki ngā taha e rua.
m=7
Tāpirihia te 2 ki te 5, ka 7.
