Choose indefinite or definite integral

I have an equation like this

$dW=x\,dx$ , where W is work.

I have find a lot on internet, but I wasn't able to find clear information. I have two questions:

1) If I want to integrate this equation, do im forced to apply definite integral or indefinite integral at the same time to each member of the equation ?

2)The right part of the integral is quite clear to me, for example I can integrate between $x=0$ and $x=5$. But in the left part, what's the meaning to integrate between (for example) $W=4$ and $W=8$ ?

If you are finding the work between two points you can integrate the right hand side from between any values of $x$.
and the left hand side between any values of $x$ as W is a function of$x$.
That being said , if you are integrating from$2$to $x$ you'll need to know the initial condition of $W(2)$.
$W(x) - W(2)=\frac{1}{2}x^2 -2$.
The text passage contains two questions about integrating an equation related to work, and it provides a partial answer to the second question.
