A graphing calculator is a more advanced calculator that can plot graphs and solve complex equations. Standard calculators do not have these abilities.

A graphing calculator is used to plot graphs and solve equations. Most graphing calculators are programmable so one can create customized programs.

No.

The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.

Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).

Graphically might be the simplest answer.

2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.

The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.

Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

If you have a TI-89: Hit "F2", select "solve." Enter your equation, which may or may not be in the following form: Then fill in values for your variables (a, b, and c) and solve for x. Your syntax will be: solve(ax^2+bx+c=0,x) * Also, if you are interested, you can download a software package for your TI graphing calculator to help you improve your score on the SAT test at www.calc-tech.com . It's called the SAT Operating System (SAT_OS) and can be used during the actual test to reduce time on math problems and improve the accuracy of your calculations.

For the most part it can. if you have a TI-83 or better, you can use the solver under your math button. All you have to do is plug in the equation that is set to equal zero!

Google has its own calculator - simply type an equation in and it will solve it straight away. To solve equations, check out wolframalpha.com

Pros: There are many real life situations in which the relationship between two variables is quadratic rather than linear. So to solve these situations quadratic equations are necessary. There is a simple equation to solve any quadratic equation. Cons: Pupils who are still studying basic mathematics will not be told how to solve quadratic equations in some circumstances - when the solutions lie in the Complex field.

Wolfram Alpha can solve not just quadratic equations, but all sorts of equations. Note that in this particular website, you can see the solution for free, but you need a paid subscription to show the steps. I am sure there are other websites that can help you as well; you may want to try a Web search for "quadratic equation", for example. On the other hand, you should definitely learn to solve quadratic equations on your own.

A quick outline of the module. Topics to by taught/ but no explainations, examples,etc. Example... It may state that students will be learning how to solve quadatic equations by graphing, factoring, completing the square, and using the quadratic formula.
