x=1/((y-2)(y-3))

Do I write simply " y<2 or 2<y<3 or 3<y" or is there a better way to express it?

Thx

There exist no strictly

x=1/((y-2)(y-3))

Do I write simply " y<2 or 2<y<3 or 3<y" or is there a better way to express it?

Thx

For example, we may write yours that "y" is an element of:

(-inf,2)U(2,3)U(3,inf)

Alternatively, we might write something like:

[tex]y\in\mathcal{R},y\neq{2},y\neq{3}[/tex]

Again, your own expression is perfectly fine.
