\sqrt{3}a-3-\frac{1}{3}a^{2}=-3
Subtract \frac{1}{3}a^{2} from both sides.
\sqrt{3}a-3-\frac{1}{3}a^{2}+3=0
Add 3 to both sides.
\sqrt{3}a-\frac{1}{3}a^{2}=0
Add -3 and 3 to get 0.
a\left(\sqrt{3}-\frac{1}{3}a\right)=0
Factor out a.
a=0 a=3\sqrt{3}
To find equation solutions, solve a=0 and \sqrt{3}-\frac{a}{3}=0.
