Linearizing this equation of a curve

[Toyona10]

Greetings~

We were told to linearize this equation below:
y= x^2/(a+bx)^2

after we multiply both the sides with the denominator (a+bx)^2, and then divide both the sides by y, can we apply ln to both the sides? Because I can see no other way of linearizing this :/

In my book, "linearizing" means that given a function y = f(x), and given a certain point x = X, you find some constants p and q such that y = f(x) ≈ p + qx when x is very close to X.

Unless you mean something else by "linearizing", I cannot see how what you have done so far could lead you to your objective.
