Classify the following polynomials as polynomials in one-variable, two-variables etc.$xy + yz + zx$
Given:
$xy + yz + zx$
To do:
We have to classify the given polynomial as polynomials in one-variable, two-variables etc.
Solution:
Variable: A variable is denoted by a symbol that can take any real value. The value of a variable is not fixed.
In $xy + yz + zx$, there are three variables $x, y$ and $z$.
Therefore, the given polynomial is a polynomial in three-variables.
