It does not matter.
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.
Factor it! Set each equal to zero! Solve
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.
To solve equations effectively in four steps, consider these types: Linear Equations: Isolate the variable by adding or subtracting terms, then divide or multiply to solve. Quadratic Equations: Rearrange to standard form, factor or use the quadratic formula, simplify, and solve for the variable. Rational Equations: Clear the denominators, simplify the resulting equation, isolate the variable, and solve. Exponential Equations: Take the logarithm of both sides, isolate the variable, and simplify to find the solution. Systems of Equations: Use substitution or elimination to reduce the system, isolate one variable, and solve for it.
Graph the equation then find the x intercepts.

Graphing
1+1=2
Graphically might be the simplest answer.
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.
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.
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.
A graphing calculator is used to plot graphs and solve equations. Most graphing calculators are programmable so one can create customized programs.
