Datrys x/9+x/b=a^2-b^2/ab

$$\frac { x } { 9 } + \frac { x } { b } = \frac { a ^ { 2 } - b ^ { 2 } } { a b }$$

Datrys ar gyfer b (complex solution)

$$\left\{\begin{matrix}b=\frac{-\sqrt{a\left(ax^{2}-324x+324a\right)}-ax}{18}\text{, }&\left(arg(a^{2})<\pi \text{ or }x\neq a\right)\text{ and }a\neq 0\\b=\frac{\sqrt{a\left(ax^{2}-324x+324a\right)}-ax}{18}\text{, }&x\neq a\text{ and }a\neq 0\end{matrix}\right.$$

Datrys ar gyfer a

$$a=\frac{-\sqrt{18bx^{2}+81x^{2}+\left(bx\right)^{2}+324b^{2}}+bx+9x}{18}$$

$$a=\frac{\sqrt{18bx^{2}+81x^{2}+\left(bx\right)^{2}+324b^{2}}+bx+9x}{18}\text{, }b\neq 0$$
