Solve for a
a=2x\left(x+1\right)
Solve for x (complex solution)
x=\frac{-\sqrt{2a+1}-1}{2}
x=\frac{\sqrt{2a+1}-1}{2}
Solve for x
x=\frac{-\sqrt{2a+1}-1}{2}
x=\frac{\sqrt{2a+1}-1}{2}\text{, }a\geq -\frac{1}{2}

-2x+a=2x^{2}
Add 2x^{2} to both sides. Anything plus zero gives itself.
a=2x^{2}+2x
Add 2x to both sides.
