Question

2. Define variable ? Give examples
3. Define term ? Give examples

4. Define Algebraic expression ? Give examples

​

Answer 1

2.A variable is a placeholder for an unknown quantity. Usually, variables are denoted by English or Greek letters or symbols such as x or θ.

Examples: In the equation 10=2x, x is the variable.

3.A term can be a constant or a variable or both in an expression. In the expression, 3a + 8, 3a and 8 are terms.

Here is another example, in which 5x and 7 are terms that form the expression 5x + 7.

4.An expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers.

For example, 2(x + 8y) is an algebraic expression.

Answer 2

Answer:

1 A Symbol for a value we don't know yet . It is usually a letter like x or y example - in x+2 = 6x is the variable.

2 A term can be a constant or a variable both in an expression . In the expression 3a + 8 , and 8 are terms.

3 Algerabic expression include at least one operation ( additional, multiplication, division)for example - 2(x+8y) is an algebraic expression .
