Th formula is PI *dia.

Pi is available on this model using Shift key + X10 key at middle bottom.

So enter Pi then key x (multiply) then enter diameter then = key.

Sorry, It is not possible to solve equations on the Casio FX-82 ms. Try the Casio FX-115 ES/ FX-115 ES Plus, FX-991ES/ FX-881 ES Plus C.

Try reseting it by pressing "shift" , "9" , and "3" in that order after you turn it on. It might fix it mine did the same thing and it fixed it.

Enter the number, press =, then press the S--D key (located above the red DEL key).

For example, to see what 25% is, type . 2 5 = S--D

Note: if you're in the LineIO mode you will see something like 1 _ 4. If you want to see it as a "real" fraction, press SHIFT MODE 1 to switch to the MathIO mode.

You don't need to calculate it. Just press

3 . 0 0 9 x10^x (-) 6

to enter the value.

x10^x is on the bottom row, to the right of the decimal point key.

(-) is on the far left column, above the RCL key.

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.
