How to avoid automatic simplification when integrating

Suppose I have the following symbolic integral

g=-(t - x)^2*((p - x1)^2 - (p - x2)^2)
int(g,t)
-((t - x)^3*(x1 - x2)*(x1 - 2*p + x2))/3

I would like the output to be

 -(t-x)^3*((p - x1)^2 - (p - x2)^2)/3

and then I would like to have

-(t-x)^3*(p - x1)^2/3 - (t-x)^3*(p - x2)^2/3

That is, I don't want polynomials to be expanded never. How can I do this?
