(April 2008) (Learn how and when to remove this template message) Trial with PC Trial and error is a fundamental method of problem solving.[1] It is characterised by repeated, varied attempts trial and error method to solve equations which are continued until success,[2] or until the agent stops trying. According to W.H. Thorpe,

the term was devised by C. Lloyd Morgan after trying out similar phrases "trial and failure" and "trial and practice".[3] Under Morgan's Canon,

the garden gate, easily misunderstood as an insightful act by someone seeing the final behaviour. Lloyd Morgan, however, had watched and recorded the series of approximations by which the dog had gradually learned the response, and could demonstrate that no insight was required to explain it. Edward Thorndike showed how to manage a trial-and-error experiment in the laboratory. In his famous experiment, a cat was placed in a series of puzzle boxes in order to trial and error method for factoring study the law of effect in learning.[4] He plotted learning curves which recorded the timing for each trial. Thorndike's key observation was that learning was promoted by positive results, which was later refined and extended by B.F. Skinner's operant conditioning. Trial and error is also a heuristic method of problem solving, repair, tuning, or obtaining knowledge. In the field of computer science, the method is called generate and test. In elementary algebra, when solving equations, it is "guess and check". This approach can be seen as one of the two basic approaches to problem solving, contrasted with an approach using insight and theory. However, there are intermediate methods which for example, use theory to guide the method, an approach known as guided empiricism.

This does not mean that the approach need be careless, for an individual can be methodical in manipulating the variables in an attempt to sort through possibilities that may result in success. Nevertheless, this method is often used by people who have little knowledge in the problem area. The trial-and-error approach has been stud

all areas of math and science. Quadratic equations are equations of the form ax2 + bx + c = 0, where a, b, and c are constants. There are several methods for solving quadratic equations, three of which we will discuss. The first method is factoring. In Section P.7, we discussed polynomial factorization and in particular, how to factor certain http://www.mathamazement.com/Lessons/Pre-Calculus/00_Prerequisites/quadratic-equations.html quadratic polynomials p(x) into two linear factors. This method can be applied to solving the quadratic equation p(x) = 0. Example 1: Solve the quadratic equation x2 - 7x + 10 = 0. Solution: By trial and error, we find x2 - 7x + 10 = (x - 2)(x - 5). Thus we have (x - 2)(x - 5) = 0. Now if the product of two expressions is zero, then at least one of the expressions must be zero. Thus we have x - 2 = 0, implying x = 2, or x - 5 trial and = 0, implying x = 5. Thus, the two solutions are x = 2 and x = 5. We may check these solutions by plugging them back into the original equation. Plugging in x = 2, we see that the left side of the quadratic equation becomes 22 - (7)(2) + 10 = 4 - 14 + 10 = 0. Substituting x = 5, we check that 52 - (7)(5) + 10 = 25 - 35 + 10 = 0. A second method of solving quadratic equations is completing the square. We use another example to trial and error illustrate this method. Example 2: Solve the quadratic equation x2 - 6x + 8 = 0. Solution: Note that by adding 1 to both sides, we obtain a square polynomial on the left, namely x2 - 6x + 9 = 1, which by identity (P.7.2b) becomes (x - 3)2 = 1. Upon computing the square root of both sides, we see that either x - 3 = 1 or x - 3 = -1. The first of these equations yields x = 4 and the second yields x = 2. Thus, the solutions of the quadratic equation are x = 2 and x = 4. It is straightforward to check these solutions. The third method for solving quadratic equations is by means of a famous formula known as the quadratic formula. The formula for solving the two roots of the quadratic equation ax2 + bx + c = 0 is as follows: (P.10.1) x = (-b ± √b2 - 4ac) / 2a. We illustrate the use of the quadratic formula with a third example. Example 3: Solve the quadratic equation 2x2 - 5x + 3 = 0. Solution: The coefficients of the quadratic polynomial are a = 2, b = -5, and c = 3. Applying the quadratic formula, we see that the roots are [-(-5) ± √(-5)2 - (4)(2)(3)] / (2)(2) = (5 ± √25 - 24) / 4 = (5 ± 1) / 4 = 1 or 3/2. Thus, the solutions are x = 1 and x = 3/2. Once again, it is straightforward to check these solutions by plugging them back into the quadratic equation. Home >> Pre-Calculus >> P. Prerequisites << P.9. Linear Equations >> P.11.
