Question about Casio FX-115ES Scientific Calculator

Hello,

The scientific prefixes are

- Giga = 1 billion ( times 1 000 000 000)
- Mega = 1 million (times 1 000 000)
- Kilo = 1 thousand (times 1000)
- deca = 10 (times 10)
- deci = one tenth ( divided by 10) or multiply by 0.1
- centi = one hyndredth (divide by 100) or multiply by 0.01.
- milli = one thousandth (divide by 1000) or multiply by 0.001
- micro = one millionth (divide by 1 000 000) or multiply by 0.000 001
- nano = one billionth (divide by 1 000 000 000) or multiply by 0.000 000 001

1L = 1000 mL

It is instructive to learn the meaning of these prefixes, because they always mean the same thing, regardless of the units you are dealing with.

Ex: The population of the Earth is about 6 Gigapersons (It does not exists, but it illustrates the principle. I hope you win a jackpot of 10 megadollars. (M$)

Hope it helps.

Milligram is a unit of mass (or weight). Milliliter is a unit of volume. The conversion depends on the density of the substance.

12 ml of water weighs 12 grams or 12,000 mg. 12 ml of gold weighs about 235 grams or 235,000 mg.

mg is a unit of mass, ml is a unit of volume. There is no conversion between them. A mg of water occupies about a ml, a mg of lead takes up a lot less space.

Sorry. It does not have a CAS. Casio Calculators with a CAS are the FX-9860G (and similar models) , FX Algebra, ClassPad 300/300PLUS//330.

Grams (g) is a unit of mass while milliliters (ml) is a unit of volume. Grams/milliliter would be a unit of density. So, you would just input 51.1/50. The units would be in g/ml.

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.
