Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
For every
, we have

So, negletting the first term, each term of the sum is greater than 1, which implies

Which means that the series diverges.

A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years
A=2500
r=0.05
n=2
t=2




divide both sides by [tex} 1.025^{4} [/tex]

The brackets are first, then the multiplication
Answer:
commission 446.9157$ or 446.92 $ and total pay 1646.92 $
