Show that:

X(squared) - 6x - 39 = 0

Thanks in advance!

for what x?
[input]solve( x^2 - 6x - 39 = 0 )[/input]

1year = 365.2425days (leap years included, gregorian calendar days)
t = 6years = 2191.455days

interest rate per day: x = 3.10% / 365.2425
C=28210.00$

compound interest P:
P = C*(1+x)t
P= 28210.00$ * (1+3.10% / 365.2425)^2191.455 = 33976.48$.

short answer:
[input]solve( y=1/(2x)+1, y=-3x+8 )[/input]

long answer:
y=1/2x+1
y=-3x+8

1/(2x)+1=-3x+8 |-1
1/(2x) = -3x+7 |*2x
1 = (-3x+7)*2x
1 = -3x*2x+7*2x
1 = -6x^2+14x |-1
-6x^2+14x-1=0
p-q-formula (quadratic formula)
=> {x=0.073760245949667, x=2.259573087383667}

now insert both "x" in one of your equations:
=> {y=1.221280737849, y=7.778719262151}

replace all "i" with "x", because i is the imaginary unit:

solve( A = P * ((x/12)/((1+(x/12)-1)^(1/360)) + (x/12)), x)
=>
x=-((((2^(1/180)*3^(1/360))*P)*x^(359/360)-(12*A))/P)

Input: lim( e^(x^2)/cos(x^2), x=0 )

Result: 1
