A monomial is a polynomial that has only one term. What is a polynomial? A polynomial is an expression containing two or more algebraic terms.
What is a variable? A variable is an alphabetic character used to represent a number that is not known. For example: x + y. The “x” and “y” are variables used in place of numeric numbers that are not known.
What is a coefficient? A coefficient is a known number that is linked to a variable. For example: 7x + 3y = 29. In this example the 7 and the 3 are coefficients because they are linked to variables. The 29 is a constant number and is not a coefficient because it is not linked to a variable.
Whenever a coefficient is linked to a variable, it is understood that the operation will be multiplied.
