Question

Using the Fundamental Theorem of Algebra determine how many possible zeros there are for each polynomial function.
1. x^5-2x+1
2. 2x+5
3. (x-5)(x+2)
4. x^2+3x-5
5. x^4-3x^2+5x-2
6. 2x(x+4)(x-7)
7. x^3-54
a. 3 Possible zeros
b. 5 Possible zeros
c. 2 Possible zeros
d. 1 Possible zero
e. 4 Possible zeros

Answer 1

number of possible zeros is simply the largest exponent x has in each expression :)
