I have this function with variable "x" and parameters "H, M, a. s," which for some reason is impossible to integrate in Mathematica so i tried to integrate with "NIntegrate" i got the anwser numerically but i can't plot it now.Please help Here's the function.

V = (-a Sqrt[(1 + 2 x) + 
 H^2/a ((3 Subscript[V, 0])/(2 (1 + 2 x)^2) - Subscript[V, 10]/(
    2 (1 + 2 x)))] + (a - 1) Sqrt[(1 + 2 x) + 
 H^2/a ((3 Subscript[V, 0])/(2 s^3 (1 - (2 x)/s)^2) - Subscript[V,
     10]/(2 s^2 (1 - (2 x)/s)))] + 1/Sqrt[1 - (2 x)/M^2])

Regards.

    The definition of V is wrong, error message $RecursionLimit::reclim2: Recursion depth of 1024 exceeded during evaluation of 1/Sqrt[1-(2 x)/M^2]. is due to Subscript[V, 10].For Mathematica it's the same variable as V. – Ulrich Neumann Apr 18 '20 at 11:57

    I avoid Subscript, except in output-formatting, so I don't have to worry about the trouble it can cause. I probably understand the issues well enough to avoid them, but why make more work for myself? Ditto for using capital-letter variables.
