Answer:
x = - 1, x = 1, x = 2
Step-by-step explanation:
The coefficients of the polynomial sum to zero, that is
- 1 + 2 + 1 - 2 = 0
This indicates that x = 1 is a zero
let x = - 1, then
- (- 1)³ + 2(- 1)² + (- 1) - 2 = 1 + 2 - 1 - 2 = 0
Thus x = - 1 is a zero
let x = 2
- (2)³ + 2(2)² + 2 - 2 = - 8 + 8 + 2 - 2 = 0
Thus x = 2 is a zero
The 3 zeros are x = - 1, x = 1, x = 2
The equation would be like this:

Answer:
C, D, B
Step-by-step explanation:
the mode is if a number is repeated more than one time
EX. 15, 23, 15, 23, 15
C because 15 is repeated 3 times and 19 is too.
D because 42 is repeated 2 times and so is 18.
B because 87 is repeated 2 times and 32 is too.
Answer:
b I think.
