Lets use the expression above to define the given terms:
1. Constant: In alebra a constant is a number on its own (Example: In the expression above 3 is a constant)
2. Variables: Quantities that may change; they are expressed as letters (Example: In the expression above x is the variable)
3. Literal coefficients: A coefficient expressed in letters (Example: In the expression above x is a literal coefficient)
4. Numerical coefficients: A constant multiplier of the variable. (Example: In the expression above 5 and 8 are numerical coefficients)
5. Algebraic expression: Combination of terms (with numerical and literal coefficients) by the operations (addition, subtraction, multiplication, etc.) (Example: The expression above is a algebraic expression)
6. Terms: Values that in a algebraic expression are separated by + or - (Example: In the expression above the terms are 5x^2, 8x and 3)
7. Polynomial: An expression with more than two terms. (Example: In the expression above there are three terms, it is a polynomial)
8. Degree of a term: The sum of the exponents of the variables in a term (Example: In the expression above first term has degree 2 and second term has a degree of 1)
9. Degree of a polynomial: Highest power of a variable in a polynomial equation. (Example: The polynomial expression above has a degree of 2)
