Answer:
Option C i.e. 2 and 9, constants have a fixed value is a correct option.
Step-by-step explanation:
In algebra, a constant is basically a fixed value.
Sometimes, a constant is a number for a letter such as a, b, or c for a fixed number.
For example: in ''2x+7=3'', 7 and 3 are constants.

In our case:
Given the equation
Therefore, 2 and 9 are constants, having a fixed value.
Thus, option C i.e. 2 and 9, constants have a fixed value is a correct option.
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,
Now, subtract 2 from the above expression,
Hence, the required expression is x²-2.
