##### How to use this applet:
The user writes a, b and c values into the textfields. They then press the "calculate roots" button and the roots are given.
If they then press the "try again" button, they are given a chance to do it again.
##### Notes on the maths used in the applet:
The roots of a quadratic equation (x1, x2), can be plotted on a graph. Negative quadratic equations (i.e -ax2 +bx +c = 0) gives a concave up curve and a positive equation gives a concave down curve.
The applet uses the formula for calcualting roots to get the x values and prints these on the screen.

GCSE Maths > Algebra - Quadratic Equations
A quadratic equation is an equation where the highest power of x is xÂ². There are various methods of solving quadratic equations, as shown below.
NOTE: If xÂ² = 36, then x = +6 or -6 (since squaring either of these numbers will give 36). However, 36 = + 6 only.
##### Completing the Square
9 and 25 can be written as 3Â² and 5Â² whereas 7 and 11 cannot be written as the square of another exact number. 9 and 25 are called perfect squares. Another example is (9/4) = (3/2)Â². In a similar way, xÂ² + 2x + 1 = (x + 1)Â².
To make xÂ² + 6x into a perfect square, we add (6Â²/4) = 9. The resulting expression, xÂ² + 6x + 9 = (x + 3)Â² and so is a perfect square. This is known as completing the square
. To complete the square in this way, we take the number before the x, square it, and divide it by 4. This technique can be used to solve quadratic equations, as demonstrated in the following example.
##### Example
Solve xÂ² - 6x + 2 = by completing the square
xÂ² - 6x = -2
[To complete the square on the LHS (left hand side), we must add 6Â²/4 = 9. We must, of course, do this to the RHS also].

 Goodness Gracious, Quadratic Functions! Click the title for a musical rendition to "Great Balls of Fire." a WebQuest for grades 9-12 Algebra by Shelli Brasher Introduction Task Resources ... Conclusion Introduction Why study quadratics? There are many ways to solve a problem. Some are more efficient than others. To design a supersonic aircraft, an engineer must select a design method that completes the job quickly and efficiently. Quadratic equations can be solved using several methods. The idea is to master these methods and learn to select the one that most efficiently solves the problem at hand. Also, the parabola, the graph of a quadratic, has numerous applications in the modern world of technology. Supersonic planes are parabolic in shape to reduce air resistance. Flashlights and satellite dish antennas have reflectors shaped like a parabola. Even the graph showing how a golf ball rises until it reaches its maximum height, then falls back to earth is shown by a parabola. The Task In this WebQuest, you will use a variety of resources to

REFERENCE
The quadratic formula is used to obtain solutions to quadratic equations. These are equations of the form
ax^2 + bx + c =
where the leading coefficient, a, is not 0.
##### Derivation of the Quadratic Formula
Solutions to the equation above have the form
x = Â­ b Â± sqrt(b^2 Â­ 4ac)/2a .
x^2 + b/ax + c/a =
Subtract c/a from both sides, x + b/ax = Â­c/a and complete the square on the left (add same term to right):
x^2 + b/ax + b^2/4a^2= Â­c/a+ b^2/4a^2
Factor the left side and combine terms on the right side:
(x + b/2a)^2 = b^2 Â­ 4ac/4a^2 Take the square root of both sides: x + b/2a = Â±sqrt(b^2 Â­ 4ac)/2a^2 The quadratic formula is then obtained by subtracting b/2a from both sides of the last equation.
##### The Discriminant
The number b^2 Â­ 4ac is called the discriminant of the quadratic. Observe that if it happens to be a negative number, then the right side of the last equation is imaginary and the solutions to the quadratic will be complex conjugates of one another. See the section on complex numbers if you need a review of how these work. You can study the

 QUADRATIC EQUATIONS TUTORIAL for Physical Sciences In physics, mathematics is used continuously. As the maths gets more tricky, it seems to lose familiarity and maths classes seem to have nothing to do with the maths in physics. Maths classes seem only to use "x, y, z" whereas physics seems to use "s, v, t, a" and other unfamiliar letters which are confusing. Physics seems to use these letters in unfamiliar orders from the familiar maths problems. Physics uses strange numbers eg decimals, not nice integers! Quadratic equations are usually the first point when physics starts using a "familiar" but otherwise purely "mathematics" type idea and suddenly this hoary old topic becomes unfamiliar. Basics - A QUADRATIC FUNCTION = anything like y = 3x - 2x + 3 or y = 3 - 2x + 3x or y = -3.42q or s = 30.2t - 4.9t (NOTICE that the ORDER of writing terms in equations is unimportant, we often forget this, we tend to think that to be a quadratic equation it has to look like .) These graphically are all PARABOLAE - any "power two" or "squared" function is a quadratic and graphs as a parabola. The largest indice term must be 2 (not three or any other number). In physics, we MODEL real phenomenon. That means we find mathematical equations that "fit" the graphs that measuring nature creates for us. We then use the algebra that "fits" to make new predictions. This is the process of modeling. The algebra we use has EXACTLY the same rules as in maths. That is why you do so much apparently useless stuff in maths ? because it is useful elsewhere, eg physics or economics.
