Whakaoti mō k
k=\frac{5x+3}{x^{2}}
x\neq 0
Whakaoti mō x (complex solution)
\left\{\begin{matrix}x=\frac{\sqrt{12k+25}+5}{2k}\text{; }x=\frac{-\sqrt{12k+25}+5}{2k}\text{, }&k\neq 0\\x=-\frac{3}{5}\text{, }&k=0\end{matrix}\right.
Whakaoti mō x

Kua tāruatia ki te papatopenga
kx^{2}=3+5x
Me tāpiri te 5x ki ngā taha e rua.
x^{2}k=5x+3
He hanga arowhānui tō te whārite.
\frac{x^{2}k}{x^{2}}=\frac{5x+3}{x^{2}}
Whakawehea ngā taha e rua ki te x^{2}.
k=\frac{5x+3}{x^{2}}
Mā te whakawehe ki te x^{2} ka wetekia te whakareanga ki te x^{2}.
