Kua tāruatia ki te papatopenga
x^{2}-2x-\frac{1}{2}x-\frac{1}{2}\left(-2\right)
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x-\frac{1}{2} ki ia tau o x-2.
x^{2}-\frac{5}{2}x-\frac{1}{2}\left(-2\right)
Pahekotia te -2x me -\frac{1}{2}x, ka -\frac{5}{2}x.
x^{2}-\frac{5}{2}x+\frac{-\left(-2\right)}{2}
Tuhia te -\frac{1}{2}\left(-2\right) hei hautanga kotahi.
x^{2}-\frac{5}{2}x+\frac{2}{2}
Whakareatia te -1 ki te -2, ka 2.
x^{2}-\frac{5}{2}x+1
Whakawehea te 2 ki te 2, kia riro ko 1.
