Answer:
x⁴ + 2 x² + 1
Step-by-step explanation:
given solution of the polynomial
i, −i, 1, −1.
equation of the polynomial will be equal to
=(x - i)(x + i)(x - 1)(x + 1)
= (x² + i x - i x - i²)(x² + x - x + 1)
=(x² - (-1))(x² + 1 )
= (x² + 1)(x² + 1)
= x⁴ + x² + x² + 1
= x⁴ + 2 x² + 1
hence, the required polynomial equation is x⁴ + 2 x² + 1

Answer:
The present value of K is, 
Step-by-step explanation:
Hi
First of all, we need to construct an equation system, so
Then we equalize both of them so we can find 
To solve it we can multiply 
to obtain 
, then we have 
.
This leads to a third-grade polynomial 
, after computing this expression, we find only one real root 
.
Finally, we replace it in (1) or (2), let's do it in (1) 
$550/people = price per person
550/25= $22 per person
550/50= $11 per person
550/55= $10 per person
