How do you solve simultaneous quadratic equations?
Graphically might be the simplest answer.
What are the pros and cons of the quadratic equation?
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.
What type of calculator is used specifically for algebra?
For basic algebra, you can use a calculator with basic functions on it used for arithmetic. If you are trying to solve more complex equations, a scientific calculator will suit you better.
How do you solve a biquadratic equation?
Equations of the form z^4+az^2+a_0 are known as biquadratic equations. They are quartic equations. In general they can be solved by reducing them to a quadratic equation where x=z^2 is the variable. Then you can use the quadratic formula or factor. So plugging in x to the biquadratic giives us x^2+ax+a_0.
What two number have the product of 121 and the sum of 22?
11 and 11. In general, you can write an equation (or two equations), and solve with the quadratic formula, to solve this type of questions.

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 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).
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 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.
How did the Babylonians solve quadratic equations?

How do you solve simultaneous quadratic equations?
Graphically might be the simplest answer.
How do you solve quadratic equations on a graphing calculator?
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 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.
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 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.
