Whakaoti mō f
f=2x-2-\frac{3}{x}
x\neq 0
Whakaoti mō x
x=\frac{-\sqrt{f^{2}+4f+28}+f+2}{4}
x=\frac{\sqrt{f^{2}+4f+28}+f+2}{4}

Kua tāruatia ki te papatopenga
xf=2x^{2}-2x-3
He hanga arowhānui tō te whārite.
\frac{xf}{x}=\frac{2x^{2}-2x-3}{x}
Whakawehea ngā taha e rua ki te x.
f=\frac{2x^{2}-2x-3}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
f=2x-2-\frac{3}{x}
Whakawehe 2x^{2}-2x-3 ki te x.
