Find the polynomial equation of least degree with roots -1, 3, and (+/-)3i
jasenka [17]
Each of these roots can be expressed as a binomial:

(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree

Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9  [since i²=-1]

Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:

(x²+9)(x²-2x-3)   [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]

x^4 -2x³-3x²
 <u>           +9x²-18x-27</u>
x^4-2x³+6x²-18x-27

\bf \qquad \textit{Amount for Exponential Decay}\\\\&#10;A=P(1 - r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{initial amount}\to &12500\\&#10;r=rate\to 9\%\to \frac{9}{100}\to &0.09\\&#10;t=\textit{elapsed time}\\&#10;\end{cases}&#10;\\\\\\&#10;A=12500(1-0.09)^t\implies A=12500(0.91)^t&#10;\\\\\\&#10;\textit{after 5 years t = 5}\qquad A=12500(0.91)^5

and surely you know how much that is.
