Question

Use the function x2 + 2x – 15 = 0

How many zeroes does the function have?
Select one:
a. 0
b. 1
c. 2
d. 3

Answer 1

the greatest power is 2 so there will be 2 answers

Answer 2

@FriedRice is correct; since the greatest power (or the degree of the polynomial) is two, then there will be two zeros. To find the zeros, you will need to factor the polynomial, which would be (x+5)(x -3). Now, set both binomials equal to zero and solve which will get you the zeros x = -5 and x = 3
