Question about Office Equipment & Supplies
The LED screen is in its last days. Replace the entire unit as the replacement circuit cost more than a new calculator.

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.

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.

Testimonial: "Thanks so much, its working now:) I thought I was going to have to buy a new calculator!"
I found it by myself, I can help you.
1. Press (AC)
2. Hold (Rate) for about 2-3 second
3. Press (Set / TAX+)
4. Input the tax rate
5. Press (Set / TAX+)
6. Hold (Rate) for about 2-3 second again
7. Press (Set / TAX+) again
And Then you can test the rate .

SOURCE: trying to calculate exponents on
If you want to get really basic and not mess around with a lot of fancy buttons and whatnot, simply put in 3.2 X 10 then push the ^ button and then (-)7. Over to the left, the third button down should look like ( - ), push that and then the 7 to avoid all the parethesis mistakes.
