any alternative method
Is there any other method to solve this(below) without using the division formula
find
$
\frac{dy}{dx}
$

if
$
y=\frac {1 +{\sqrt{x}}}{1 -{\sqrt{x}}}

Perhaps multiply above and below by ${1 +{\sqrt{x}}}$ and simplify?
Or use the product rule with $({1 - \sqrt{x}})^{-1}$..
Had you a particular method in mind?
