Using Descartes' rule of signs
look for the number of sign changes in f(x)
+ / + / - / -
There is 1 sign change hence 1 positive zero
f(-x) = -x³ + x² + 8x - 8
look for the number of sign changes in f(- x)
- / + / + / -
there are 2 sign changes hence 2 possible negative zeros
Answer:
If I am right you have to multiply 8 by 30 and than divide it by 12 the answer it will give you is x
12 payments of 211 because interest is primarily based on how long it will take you to pay back the loan, so the longer you take, the more interest you pay
