Solve for a
\left\{\begin{matrix}a=0\text{, }&b\neq 0\\a\in \mathrm{R}\text{, }&b=\frac{\sqrt{17}-1}{4}\text{ or }b=\frac{-\sqrt{17}-1}{4}\end{matrix}\right.
Solve for b
\left\{\begin{matrix}\\b=\frac{\sqrt{17}-1}{4}\text{; }b=\frac{-\sqrt{17}-1}{4}\text{, }&\text{unconditionally}\\b\neq 0\text{, }&a=0\end{matrix}\right.

2a-ba=a\times 2b^{2}
Multiply both sides of the equation by 2b^{2}, the least common multiple of bb,2b.
2a-ba-a\times 2b^{2}=0
Subtract a\times 2b^{2} from both sides.
2a-ba-2ab^{2}=0
Multiply -1 and 2 to get -2.
\left(2-b-2b^{2}\right)a=0
Combine all terms containing a.
a=0
Divide 0 by 2-b-2b^{2}.
