5 raruraru e ōrite ana ki:
\frac { 2 ( x + 1 ) } { ( 2 x + 5 ) ( x + 2 ) } = 0
Tohaina
Kua tāruatia ki te papatopenga
2\left(x+1\right)=0
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -\frac{5}{2},-2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te \left(x+2\right)\left(2x+5\right).
2x+2=0
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2}{2}
Whakawehea ngā taha e rua ki te 2.
x=-1
Whakawehea te -2 ki te 2, kia riro ko -1.
