more information
These are the important concepts we need to be aware of:
POLYNOMIAL: Is the addition of subtraction of different terms.
Remember to write the polynomial in descending order of exponents.
TERM: A term is made up of number and a variable. The variable is raised to a power. That is, the variable has an exponent.
- Remember that the if a term does not have a written number, it means that its number is 1
- Also, a term that has no variable, in reality, has a variable with an exponent of 0 (because anything to the power of 0 is 1!)
DEGREE: Of a term - Is the variable's exponent
- Of a polynomial: It is the highest exponent in the polynomial
NUMERICAL COEFFICIENTS: Are the numbers which multiply the variable in a term.
CONSTANT: It is the term in a polynomial that has no variable. It is called so because it does not change.
IMPORTANT
1. The terms in a polynomial must be written from the highest exponent to the lowest exponent (descending order).
2. If the degree (exponent) is the same between 2 terms, the terms are written in alphabetical order.
