got some questions....need ur help

Q1>>> Show that the two tangents to the curve ax^2+2hxy+by^2=1, a>0? at the points,where the curve crosses x-axis, are parallel.

Q2>>> If f(x)-[a+x/b+x]^a+b+2x then find f'(x) at x=0.

$Q_{2}$

Like this?

$f(x)-(\frac{a+x}{b+x})^{a+b+2x}$

or?

$f(x)=(\frac{a+x}{b+x})^{a+b+2x}$
