1. 3x - 1....there are 2 terms...(3x) and (1)
2. the constant....a number that stands by itself, with no variable attached.
-2x + 1...constant is 1
3. coefficient....a number that is multiplied by a variable (a letter)
having trouble understanding this problem...is it -x^7 + 3 ? if so, the coefficient is -1. If it is -7x + 3, the coefficient is -7
4. factors of 2x^5 - 8 ...there are 3 factors, 2, x^5, and -8
5. not sure what ur asking.
