In any scientific calculator log2(n) can be calculated with either ln or log function as
Log2(n)= ln(n) / ln(2)
Log2(n)=log(n) / log(2)
both will give nearly the same answers

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.
To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.
Hope it helps.

There is a function to calculate them for you.
In CAS, or Algebra or Tutor Modes, use the x! option
In Run-Math, press [OPTN][F6] to pan right, then [F1] to access the (PROB) menu then enter option number corresponding to x!
The way it works is as follows
number ! [EXE].
Due to memory limitations, you can calculate factorials of numbers up to 69.
Hope it helps.
