Variable as Coefficient of Variable

Before you go through this topic, you must know : What are Constants ? What are Variables ? Variable as Coefficients of Variable :- This situation occurs when an algebraic expression contains a constant and two or more variables. For example :- In an algebraic expression 45ab, we have :- Variables = a, b and Constant = 45, 45a is the coefficient of variable b and......... (1) 45b is the coefficient of variable a...........(2) So from (1) and (2), we can learn that A Coefficient can also have a Variable. Following examples can further explain How a Coefficient of a variable can have a Variable - Example 1 = Find the coefficient of variable x in an algebraic expression 4xy. Answer = 4y is the coefficient of variable x and contains :- Constant = 4 and Variable = y So, a coefficient of variable x contains a variable y Hence we can say that A Coefficient can also have a Variable. Example 2 = Find the coefficient of variable p in an algebraic expression 26pq. Answer = 26q is the coefficient of variable p and contains :- Constant = 26 and Variable = q So, a coefficient of variable p contains a variable q Hence we can say that A Coefficient can also have a Variable. Example 3 = Find the coefficient of variable b in an algebraic expression 100abc. Answer = 26q is the coefficient of variable p and contains :- Constant = 100 and Variables = a, c So, a coefficient of variable b contains variables a and c Hence we can say that A Coefficient can also have a Variable.
