To expand the expression x + h³, we simply need to identify the terms involved. In this case, the expression consists of two distinct parts: x and h³.
Since there are no like terms to combine or any operations to perform on them, the expansion is quite straightforward. The expression x + h³ remains as it is.
This means that the expanded form of the expression is simply:
x + h³
In summary, when we say ‘expand,’ we often look for products, powers, or binomials to work with. However, in this case, the expression is already in its simplest form, and thus requires no additional expansion.
