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.

Hello,
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.

Hello,
Use the FIX display format and set the number of decimal digits to be displayed to be 2 o 3 or more depending on your needs. Instructions are on screen capture below. Hope it helps.

### I do not know what a range is and where to find it on a Casio FX 9750GII Calculator

In statistics, the range of 1-var a data set is the difference between the largest value and the smallest. R=Xmax-Xmin
In functions: the range of a function is the interval (or the Union of intervals) of the real line where the dependent variable takes it values.
Ex: sin(x). Whatever the value of the independent variable x, the values of the function sin(x) are in the closed interval [-1,1]. The range of the functions sin(x), and cos(x) is [-1,1].
No use of a calculator for finding the range of functions.

It is a calculator and prqactically every button is a MATH button. It depends on what MATH you intend to do. Put the calculator in Run/Mat screen then press the OPTN key. You will see several tabs. Press the function key under a TAB and explore what is offered. Go through all the keys (F6 also) and see what the new tabs do.
In general it is most helpful to read the manual that shipped with the calculator.

### How do i use the fx-300es to graph

Sorry but you cannot do that. This is not a graphing calculator. However you can generate a table of values for your function (MODE TABLE) and use it to graph the curve by hand (pencil and paper).

If you need a Casio graphing calculator, one of the cheaper ones is the Casio FX-9750GII. Equivalent Texas Instruments calculators are the TI83PLUS/TI84PLUS.
