HELP. Write key ideas or a short summary about algebraic notation.

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.

y=sec x is the correct answer
