Answer:
Coefficients
In Algebra we work with Variable, Symbols or Letters whose value is unknown to us.
Algebraic Expression
In the above expression (i.e. 5x – 3),
x is a variable, whose value is unknown to us which can take any value.
5 is known as the coefficient of x, as it is a constant value used with the variable term and is well defined.
3 is the constant value term which has a definite value.
The whole expression is known to be the Binomial term, as it has two unlikely terms.
