Classify 4n3+6 by degree. ____ by number of terms _____. Trying to help my son and I don't have a clue...
ok, so do you know what a polynomial is?
No
The degree of a number is the highest term in the polynomial or term with the highest exponent whats the highest exponent? 4n^3 is one term +6 is another term how many terms are there?
Polynomial comes from poly- (meaning "many") and -nomial (in this case meaning "term") ... so it says "many terms" http://www.mathsisfun.com/algebra/polynomials.html
2 terms
ok so, a polynomial is something that looks like this: \[a_0+a_1x+a_2x^2+...+a_na^n\]
The degree, or order of the polynomial is the n term(ie the largest exponent)
Okay
So then, once you decide you have a polynomial, you can count how many unique(I'll explain that in a sec) terms you have
unique means that no two terms have the same exponent ie \(x^2\) and \(5x^2\) are not unique
The coefficient on the term,(the a's in the general form) have no weight when determining how many terms you have
so then, once you count your terms, you have to apply the more specific name, to a polynomial, as mentioned just means multiple. It is the most general classification
so, now the prefix there is poly- Once you decide how many terms you have, just apply the appropriate prefix that corresponds to that number. Let me know what you think it may be here
