Hello, can any one help me solve for x by this equation:
2 (1+ x^2)^2 = 10x
I have no ideas ????
and how to draw f(x) = 2x / (1+x^2)^2
I'm using the calculator but did not get a clear pics for [0,2]

$\displaystyle 2 (1+ x^2)^2 = 10x$ has a very long exact solution. You could use an approximation method to find the approxiamate value of x to however many decimal places you want, like the Newton-Raphson Method.
Is it me or is what you are asking really confusing?
I'll do my best:
$\displaystyle \displaystyle \int_0^2 \frac{2x}{(1+x^2)^2}dx \ne \frac{2}{5}$
The integral from 0 to 2 doesn't equal 2/5. Can you show us what you did to get 2/5?
In the equation $\displaystyle f(x) = 2x / (1+x^2)^2$ where you substitute in values for f(x) and solve for x to get f(c), there will be no simple solution.
You can use approximation methods to find the values of f(c) to put into your graph, however I see no real solutions in what you are trying to calculate.
