Tohaina
Kua tāruatia ki te papatopenga
0xy+\frac{1}{2}a+2xy-\frac{5}{2}a+2
Whakareatia te 0 ki te 3, ka 0.
0+\frac{1}{2}a+2xy-\frac{5}{2}a+2
Ko te tau i whakarea ki te kore ka hua ko te kore.
0-2a+2xy+2
Pahekotia te \frac{1}{2}a me -\frac{5}{2}a, ka -2a.
2-2a+2xy
Tāpirihia te 0 ki te 2, ka 2.
\frac{0+a+4xy-5a+4}{2}
Tauwehea te \frac{1}{2}.
4xy-4a+4
Whakaarohia te a+4xy-5a+4. Whakarea ka paheko i ngā kīanga tau ōrite.
4\left(xy-a+1\right)
Whakaarohia te 4xy-4a+4. Tauwehea te 4.
2\left(xy-a+1\right)
Me tuhi anō te kīanga whakatauwehe katoa.
