A variable is a symbol or letter, such as $x$ or $y$, that represents a value. In algebraic equations, the value of one variable is often dependent on the value of another. Hence it's a symbol that takes various numerical values.

The constant in the polynomial $x + 5$ is $5$.

Both the terms in the given expression contain atleast one variable, $x$ and $xy$..

The variables used are $x$ and $y$.

For a particular polynomial, its constant cannot change otherwise polynomial will change.

The terms $y^{3}, y^{2}$ and $y$ are not constants. 

The value of the polynomial changes as the variable changes. 

The value of the polynomial changes as the variable changes. 

al-Khwarizmi is the father of Algebra.

An important development in algebra in the $16^{th}$ century was the introduction to unknown symbols.
