Solve for k
k=-a\left(a-x\right)
Solve for a (complex solution)
a=\frac{\sqrt{x^{2}-4k}+x}{2}
a=\frac{-\sqrt{x^{2}-4k}+x}{2}
Solve for a
a=\frac{\sqrt{x^{2}-4k}+x}{2}
a=\frac{-\sqrt{x^{2}-4k}+x}{2}\text{, }k\leq \frac{x^{2}}{4}

-ax+k=-a^{2}
Subtract a^{2} from both sides. Anything subtracted from zero gives its negation.
k=-a^{2}+ax
Add ax to both sides.
