Quadratic equations do not always occur in standard form. Sometimes they have to be converted to standard form using our basic principle of doing the same thing on both sides to get where we want to go. The equation $$x+\frac{1}{x} = 2$$ has only one solution. It is
$x=$.
Hint: When you see the solution you will say "of course". As a first step, multiply with $x$ on both sides.
