Tohaina
Kua tāruatia ki te papatopenga
2xy-15x^{2}+\frac{1}{2}\times 2y+\frac{1}{2}\left(-15\right)x
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x+\frac{1}{2} ki ia tau o 2y-15x.
2xy-15x^{2}+y+\frac{1}{2}\left(-15\right)x
Me whakakore te 2 me te 2.
2xy-15x^{2}+y+\frac{-15}{2}x
Whakareatia te \frac{1}{2} ki te -15, ka \frac{-15}{2}.
2xy-15x^{2}+y-\frac{15}{2}x
Ka taea te hautanga \frac{-15}{2} te tuhi anō ko -\frac{15}{2} mā te tango i te tohu tōraro.
