Solve for b
b=-a+\frac{2}{a}
a\neq 0
Solve for a
a=\frac{\sqrt{b^{2}+8}-b}{2}
a=\frac{-\sqrt{b^{2}+8}-b}{2}

aa+ab=2
Multiply both sides of the equation by a.
a^{2}+ab=2
Multiply a and a to get a^{2}.
ab=2-a^{2}
Subtract a^{2} from both sides.
\frac{ab}{a}=\frac{2-a^{2}}{a}
Divide both sides by a.
b=\frac{2-a^{2}}{a}
Dividing by a undoes the multiplication by a.
b=-a+\frac{2}{a}
Divide 2-a^{2} by a.
