What is this presentation for?

You can found a shiny application on the web which

  • help you to solve your quadratic equation
  • gives you how many solvation has your equation
  • gives you \( x_1 \), and \( x_2 \) of your equation

About quadratic equations

In elementary algebra, a quadratic equation is any equation having the form

\( a*x^2 + b*x + c = 0 \)

where x represents an unknown, and a, b, and c represent known numbers such that a is not equal to 0. If a = 0, then the equation is linear, not quadratic. The numbers a, b, and c are the coefficients of the equation, and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.
(from http://en.wikipedia.org/wiki/Quadratic_equation)

How does it work?

Step 1

Recognize a, b, c of your equation.

Step 2

Fill the a, b, c values into side bar panel. Dont't forget to write (-) if you have negative value.

Step 3

Push the 'Submit' button.

Step 4

Check returned values.

Step 5

Get the x values of your equation.

Question for you

Do you know how many solution has the equation \( 3*x^2 + 5*x + 7 = 0 \) ?

Remember the solving formula is \( \frac{-b \pm \sqrt{b^2-4*a*c}}{2*a} \)
