Los 2/5nx-n^2/x+x/10=7/15-frac{x}{3}+frac{nx}{2} op

$$\frac { 2 } { 5 } n x - \frac { n ^ { 2 } } { x } + \frac { x } { 10 } = \frac { 7 } { 15 } - \frac { x } { 3 } + \frac { n x } { 2 }$$

Oplossen voor n (complex solution)

$$n=-\frac{\sqrt{9x^{4}+1560x^{2}-1680x}}{60}-\frac{x^{2}}{20}$$

$$n=\frac{\sqrt{9x^{4}+1560x^{2}-1680x}}{60}-\frac{x^{2}}{20}\text{, }x\neq 0$$
