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...

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.
