-3x C. x-2 +7 D. √2x2 +1/2​

Answer 1

Answer:

A .xy

Step-by-step explanation:

xy isthe polynomial

Answer 2

$\frac{x}{y}$ is the polynomial

Explanation:

• Polynomials refer to that mathematical expression that comprises more than one variable.
• For example $3x +2, 4y -76$ etc.
• So option A has more than one variable in the form of $x$ and $y$.
• Whereas in other options there is a single variable that is $x$

• No matter how long a number or an expression is. It is considered to be a polynomial only when it will have more than one variable.
