I stumble a question I cannot answer please help up.

Question

Find value of lower and upper limit of k for equation:

(3x^3-5)/x^2 dx = 10

limit: -k , k

Answer 1

Also:
Is this
(3x^3-5)/(x^2 dx) = 10
which is
3x^3-5 = 10 x^2 dx

or is this
[(3x^3-5)/x^2] dx = 10
which is
3 x dx - 5dx/x^2 = 10

Now what is k ? and do you want to integrate something here? I have a feeling that you are only posting part of the problem.
