Lutasin ang y=4x^4+4/5quad(y+1)^2/y=?

$$y = \frac { 4 x ^ { 4 } + 4 } { 5 } \quad \frac { ( y + 1 ) ^ { 2 } } { y } = ?$$

I-solve ang x (complex solution)

$$x=\left(-\frac{1}{2}+\frac{1}{2}i\right)\left(y+1\right)^{-\frac{1}{2}}\sqrt[4]{4+8y-y^{2}}$$

$$x=\left(\frac{1}{2}+\frac{1}{2}i\right)\left(y+1\right)^{-\frac{1}{2}}\sqrt[4]{4+8y-y^{2}}$$

$$x=\left(-\frac{1}{2}-\frac{1}{2}i\right)\left(y+1\right)^{-\frac{1}{2}}\sqrt[4]{4+8y-y^{2}}$$

$$x=\left(\frac{1}{2}-\frac{1}{2}i\right)\left(y+1\right)^{-\frac{1}{2}}\sqrt[4]{4+8y-y^{2}}\text{, }y\neq -1\text{ and }y\neq 0$$
