Changing index of an integral


As source i have the gauss quadrature integral:

Now I've seen that, to be able to use that in the range between 0 and , where z is less or equal, i could shift the integral which results in

Now the integral always goes from 0 to z. What do i have to do when i want it to go from x to z something like this:

Do i have to transform the integral again, and how does that exactly work. Or do i have to do this: where i subtract the result of the first integral from the second.

In the end this is to calculate the arc-lengths of the segments of a cubic bezier curve.
