Whakaoti mō F
F=x-\frac{4}{x}
x\neq 0
Whakaoti mō x
x=\frac{-\sqrt{F^{2}+16}+F}{2}
x=\frac{\sqrt{F^{2}+16}+F}{2}
Graph
Tohaina
Kua tāruatia ki te papatopenga
Fx=x^{2}-4
Whakaraupapatia anō ngā kīanga tau.
xF=x^{2}-4
He hanga arowhānui tō te whārite.
\frac{xF}{x}=\frac{x^{2}-4}{x}
Whakawehea ngā taha e rua ki te x.
F=\frac{x^{2}-4}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
F=x-\frac{4}{x}
Whakawehe x^{2}-4 ki te x.
