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.

What can one use an online graphing calculator for?
A graphing calculator is used to plot graphs and solve equations. Most graphing calculators are programmable so one can create customized programs.
What is the quadratic formula for?
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.
Why do you use square roots to solve quadratic equations?
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

y=3x-4 y=-2x+1
Why use graphing to solve a system of equations?
A graph can help you understand equations better its a little way of getting used to a a problem. I used a multiplication graph when i was 10 it helped me memorize the problem.
How do you use a graphing calculator to solve quadratic equations?

What is the function of graphing calculators?
A graphing calculator is a calculator with the capability of graphing an equation on a built-in coordinate grid on the screen. They usually have a simple LCD grid screen, and by typing in the equation (e.g., 5x+3), the screen refreshes to display a graph of the equation in a set window range.
What is the advantage that the method od substitution has over the graphing method of solving system of equations?
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).
How do you solve equations on a TI-83 graphing calculator?
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.
In mathematics how does one use the quadratic formula?
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.
How did the Babylonians solve quadratic equations?
1+1=2
How do you solve simultaneous quadratic equations?
Graphically might be the simplest answer.
Can a graphing calculator be used to solve any quadratic equation?
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!
What is the quadratic formula for?
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.
What is the quadratic equation used for?
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.
