Answer:
P(x) =
- 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x =
, x = - 
Then the factors are (x - 2), (x + 2), (x -
), (x +
)
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x -
)(x +
) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
=
- 3x² - 4x² + 12 ← collect like terms
=
- 7x² + 12

Answer: 13% or 0.1314
Step-by-step explanation: Binomial PDF on the calculator or by hand its

Compute each option
option A: simple interest
simple interest is easy
A=I+P
A=Final amount
I=interest
P=principal (amount initially put in)
and I=PRT
P=principal
R=rate in decimal
T=time in years
so given
P=15000
R=3.2% or 0.032 in deecimal form
T=10
A=I+P
A=PRT+P
A=(15000)(0.032)(10)+15000
A=4800+15000
A=19800
Simple interst pays $19,800 in 10 years
Option B: compound interest
for interest compounded yearly, the formula is

where A=final amount
P=principal
r=rate in decimal form
t=time in years
given
P=15000
r=4.1% or 0.041
t=10


use your calculator
A=22418.0872024
so after 10 years, she will have $22,418.09 in the compounded interest account
in 10 years, the investment in the simple interest account will be worth $19,800 and the investment in the compounded interest account will be worth$22,418.09
