Question 1.

Can you identify the terms, variables and coefficients of this algebraic expression? Class 9

Answer:

In the expression 10x - x², there are two terms 10x and -x².

The variable representing the length of the rectangle is x.

The coefficient of x is 10 and the coefficient of x² is -1.

Question 2.

Can you point out any similarity or difference between the algebraic expressions obtained in Examples 1 and 3 Class 9

Answer:

Similarity: Both are algebraic expressions with variable terms, and both have two terms involving variables.

Differences:

Number of variables: Example 1 uses two variables x and y, while Example 3 uses only one variable (x).

Constant term: Example 1 includes a constant term of 3, but Example 3 does not have any constant term.
