Expand (what does expand mean in relation to the below problem?)

----------------------
= y^0 = 1, and 1/z^-2 = z^2
= z^2 cancels
= (2x^-2)^-1 = x^2/2
=
=
=
=
=
=
----------------
Expand is multiplying terms, usually binomials or larger. This problem was mostly simplification, tho, combining terms.
