Two different (isomorphic) splitting field

Question

how I write in the title, studying the splitting field, I read there are a lot of extension of a field $\mathbb{K}$ in which $f(x)\in\mathbb{K}[x]$ can be write as a product of linear polynomials, minimal extension in the sense of inclusion. I know that this extensions are isomorphic, but I ask an example of two different extension.
