Cari nilai y
y=x\left(5x+7\right)
x\neq 0
Cari nilai x (complex solution)
\left\{\begin{matrix}\\x=\frac{-\sqrt{20y+49}-7}{10}\text{, }&\text{unconditionally}\\x=\frac{\sqrt{20y+49}-7}{10}\text{, }&y\neq 0\end{matrix}\right,
Cari nilai x
\left\{\begin{matrix}x=\frac{-\sqrt{20y+49}-7}{10}\text{, }&y\geq -\frac{49}{20}\\x=\frac{\sqrt{20y+49}-7}{10}\text{, }&y\neq 0\text{ and }y\geq -\frac{49}{20}\end{matrix}\right,
