d x = x ^ { 2 } - 3
Solve for d
d=x-\frac{3}{x}
x\neq 0
Solve for x
x=\frac{-\sqrt{d^{2}+12}+d}{2}
x=\frac{\sqrt{d^{2}+12}+d}{2}

xd=x^{2}-3
The equation is in standard form.
\frac{xd}{x}=\frac{x^{2}-3}{x}
Divide both sides by x.
d=\frac{x^{2}-3}{x}
Dividing by x undoes the multiplication by x.
d=x-\frac{3}{x}
Divide x^{2}-3 by x.
