With the right tools, complex mathematics and scientific calculations can be done quickly and efficiently, with a high level of accuracy that presents reliable solutions.

Sophisticated hand-held calculators can accomplish such tasks, as can __online sites__ with available templates for solving quadratic equation calculations. These tools of course rely on immediate internet availability, an obvious drawback.

Not all electronics manufacturers offer devices that may serve your purposes as calculators for solving quadratic equations, so the key questions prior to making a purchase is to understand:

- What are your specific needs?
- Will the calculator you have in mind do the job, and how easily?

**First – What do You Need?**

Many scientific calculators can perform reasonably sophisticated math problems, as well as performing graphic functions. But not all can solve quadratic equations.

Many, like the __TI 83/84__ can be programmed to solve quadratic equations, but first you need to know how to solve them yourself, in order to create the program. Note – scouring the web reveals numerous programs available from TI 83/84 owners who are willing to share their programming accomplishments, including an application that solves quadratic equations.

If the native ability to solving such equations is at the top of your list, check the manufacturer’s specifications to ensure those functions exist with a minimum of effort on your part.

Some quadratic equations can be solved using factoring, but not all units on the market are factoring quadratic equations calculators. Factoring is a common method applied as a step in solving equations through first factoring the expressions to arrive at the answer to the problem.

**Next – Models That do the Job**

There are a considerable number of scientific calculators very capable of handling quadratic equations, with some providing factoring functions, allowing expressions to be factored.

__Casio FX-9750GII__ – this powerful calculator performs scientific calculations and graphing functions, including statistical regression, logarithmic, and quadratic functions. Support is also included for complex number calculations, polynomial equations, and factorial, inverse, and random numbers.

__Casio FX CG models__ – Casio offers a range of units in the FX CG line, with an array of features that include:

- 3D color graphics
- Over 2900 available functions
- Toggling between graphic display and expressions
- Factorial, random, and inverse number handling
- Complex number and Base-n calculations
- Statistical regression including linear and quadratic

__Sciencing.com__ offers tips on solving quadratic equations utilizing a variety of Casio calculators.

Texas Instruments similarly has a variety of powerful devices that are quadratic equation factoring calculators.

__TI 83/84 models__ offer an impressive set of features that should also solve all your scientific, graphing, and mathematic function requirements:

- Backlit hi-res display – some models with color displays
- Pre-loaded applications ready to use
- Ability to import photos for graphing overlays to enhance viewing impact
- Interactive equation solver editor – makes changing variables simple
- Advanced statistics including multiple hypothesis testing functions
- Logistic, linear, logarithmic, and quadratic polynomial models, and more
- Business, classroom, and scientific applications

__TI Nspire models__ provide flexibility and power in a hand-held calculator, offering a considerable range of features:

- Linear, exponential, and quadratic functions and equations
- Hi-resolution backlit color display
- Rechargeable batteries via USB, docking station, or wall charger
- Interactive built-in geometric functions

__HP Prime__ – long known for their prowess in building hi-tech equipment, HP’s calculator offerings include the Prime scientific graphing calculator, with an array of features that does not disappoint:

- Full graphing functions including polar, parametric plot, histogram, and much more
- Scientific functions for base conversions and arithmetic, polar/rectangular conversions, and Boolean graphics
- Complex number functions, fractional numbers, hyperbolics, symbolic integration, and additional math functions

Manufacturers make your comparison easy though online product finders such as __Casio’s site__ or the __Texas Instruments__ online catalog.

**More Than One Way to Solve a Problem**

There are a considerable number of options when it comes to selecting a scientific/graphing calculator. If your main concern is finding the best quadratic equation solving calculator, and one that supports factoring functions, make sure the model you choose provides those capabilities with ease of use.

Consider though that many offerings have other features and functions that may outweigh other short-comings. It may be to your benefit to pick a calculator that has extra features such as larger screens and more memory to store your programs, even if it means a couple of extra steps to accomplish solving quadratic equations.

**Summing Up**

All scientific calculators are not created equal. Once you’re determined what your own requirements are for solving and factoring quadratic equations, compare models for their capabilities. Consider ease of use and potential for future needs (upgradable software, ability to load and run shared programs, etc).

While price is certainly a factor in your purchasing equation, it should not be your only consideration.
