Answer:
x=-1, x=3 e x=2i, x=-2i
Step-by-step explanation:
Solve for x over the real numbers:
x^4 - 2 x^3 + x^2 - 8 x - 12 = 0
The left hand side factors into a product with three terms:
(x - 3) (x + 1) (x^2 + 4) = 0
Split into three equations:
x - 3 = 0 or x + 1 = 0 or x^2 + 4 = 0
Add 3 to both sides:
x = 3 or x + 1 = 0 or x^2 + 4 = 0
Subtract 1 from both sides:
x = 3 or x = -1 or x^2 + 4 = 0
Subtract 4 from both sides:
x = 3 or x = -1 or x^2 = -4
x^2 = -4 has no solution since for all x on the real line, x^2 >=0 and -4<0:

Answer:
Her proximate APR is 5.1%
Step-by-step explanation:
The formula of the APR is × × 100%, where
- FC is the finance charge
- A is the amount financed
- m is the number of months
∵ Whitney bought a watch for $107.5
∴ A = 107.5
∵ The finance charge was $11
∴ FC = 11
∵ She paid for it over 6 months
∴ m = 6
- Substitute these values in the formula above
∵ × × 100%
∴ APR = 5.11627907%
- Round it to the nearest tenth
∴ APR = 5.1%
Her proximate APR is 5.1%
