How do you solve a quadratic equation?
There are many ways to solve a quadratic equation, but the quadratic formula works for all equations and is very quick. The formula isx= -b +/- the square root of (b^2 - 4ac)_________________________________2aTo find a,b, and c refer to the layout of a quadratic equation:ax2 + bx +cNew Answer (from Nghi1350).If the given quadratic equation can be factored, you can solve it faster by using the factoring "ac method" (You Tube) or by the new Diagonal Sum method (Amazon e-book 2010).Otherwise, use the quadratic formula. There is an improved quadratic formula that is easier to remember presented in the above mentioned book. This formula is called the "Quadratic formula in graphic form", since it relates the real roots to the x-intercepts of the parabola graph of the quadratic function.The 2 real roots are given by this formula:x1 = - b/2a + d/2a ; and x2 = -b/2a - d/2a. (1)The quantity (-b/2a) represents the x-coordinate of the symmetry axis of the parabola.The 2 quantities (d/2a) and (-d/2a) represent the 2 distances from this axis to the two x-intercepts of the parabola.The quantity (d) can be zero, a number, or imaginary.- If d = 0; there is double root at x = -b/2a- If d is a number (real or radical): there are 2 real roots.- If d is imaginary: There are no real roots.The quantity (d) is given by the relation (2), obtained by writing that the product of the 2 real roots is equal to (c/a):[(-b - d)/2a][-b + d)/2a] = c/ab^2 - d^2 = 4acd^2 = b^2 - 4ac (2)To solve a quadratic equation, first find d by the relation (2) then find the real roots by the formula (1).This new improved quadratic formula is easier to remember since you can relate it to the x-intercepts of the parabola graph. In addition, the quantity (d/2a) makes more sense about distance than the classical quantity "square root of b^2 - 4ac".

What are the applications of quadratic equations in every day life?
Police, Quadratics, Action! If you know the initial speed of car, how far you are travelling and what your acceleration is, there is a special formula that lets you find out how long the journey will take. This formula is a quadratic with time as its unknown quadratic quantity. The police use this equation - along with many other quadratic and non-quadratic equations - when they attend a road traffic accident (RTA). They do this to find out if the driver was breaking the speed limit or driving without due care and attention. They can discover how fast the car was going at the time the driver started braking and how long they were braking for before they had the accident. This is done by finding the road's coefficient of friction and by measuring the length of the skid marks of the vehicles involved. Once they have this information they turn to Mathematics and the trusted quadratic equation. Einstein's Famous Quadratic The most famous equation in the world is technically quadratic. Einstein discovered the formula: Where E is the Energy of an object, m is its mass and c is the speed of light. This formula relates mass and energy and came from Einstein's work on Special and General Relativity. However, in practice it is not solved as a quadratic equation as we know the value of the speed of light. For more information on Einstein and his Theory of Special Relativity see the links at the bottom of the page. There are many more uses for quadratic equations.
