Answer

To fill in the blanks for the question "An algebraic expression involves ___________, ___________ and _____________," we can follow these steps:

1. **Identify the components of an algebraic expression**: An algebraic expression is made up of variables, constants, and operators.

2. **Fill in the first blank**: The first component is a variable. We can use "x" as an example of a variable.

3. **Fill in the second blank**: The second component is also a variable. We can use "y" as another example of a variable.

4. **Fill in the third blank**: The third component is a constant. A constant is a fixed value that does not change, so we can use "1" as an example of a constant.

Putting it all together, we can fill in the blanks as follows:

An algebraic expression involves **variables**, **variables**, and **constants**.

Final answer: An algebraic expression involves **x**, **y**, and **1**.
