What is the common tangent to the parabolas #y^2=4ax# and #x^2=4by# ?
and as it is a tangent, we should have discriminant zero i.e.
graph{(y^2-4x)(x^2-8y)(root(3)2y+x+root(3)4)=0 [-5.416, 4.584, -2.8, 2.2]}

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
