How to get the decision of integral in a symbolic form?

Mathematica gives an answer for indefinite integral. I got expression in the second line after the expansion of the limits. But I can`t plot with this expression. The plot appears for expression in the third line. Is it possible to get the decision of this integral any other way? Thank you.

According to Mathcad's numerical calculations the three expressions you have listed are all different! See attached.

You have three unspecified variables. Which do you want to plot against?

Why do you need a symbolic result if you just want plots - you could plot using numerics.

Thank for your answer. I need decision of integral in first line. A,b,c are constant and independent from variable x. I need plot result of this integral. So I can get result in simbolic form.

The integral in your file goes from 0 to infinity, so it has a single value. Do you mean the upper limit to be some finite value, x, and you want to plot the value of the integral as a function of this upper limit?
