method. Trial and Improvement Any equation can be solved by trial and improvement (/error). However, trial method in algebra this is a tedious procedure. Start by estimating the solution (you may be given this estimate). Then substitute this into the equation to trial and error method in feed formulation determine whether your estimate is too high or too low. Refine your estimate and repeat the process. Example Solve t³ + t = 17 by trial and improvement. Firstly, select a value of t to try in https://www.youtube.com/watch?v=Up-6LkPG1XM the equation. I have selected t = 2. Put this value into the equation. We are trying to get the answer of 17. If t = 2, then t³ + t = 2³ + 2 = 10 . This is lower than 17, so we try a higher value for t. If t = 2.5, t³ + t = 18.125 (too high) If t = 2.4, t³ + t = 16.224 (too low) If https://revisionmaths.com/gcse-maths-revision/algebra/solving-equations t = 2.45, t³ + t = 17.156 (too high) If t = 2.44, t³ + t = 16.966 (too low) If t = 2.445, t³ + t = 17.061 (too high) So we know that t is between 2.44 and 2.445. So to 2 decimal places, t = 2.44. Iteration This is a way of solving equations. It involves rearranging the equation you are trying to solve to give an iteration formula. This is then used repeatedly (using an estimate to start with) to get closer and closer to the answer. An iteration formula might look like the following (this is for the equation x2 = 2x + 1): xn+1 = 2 + 1 xn You are usually given a starting value, which is called 0. If x0 = 3, substitute 3 into the original equation where it says xn. This will give you x1. (This is because if n = 0, x1 = 2 + 1/x0 and x0 = 3). x1 = 2 + 1/3 = 2.333 333 (by substituting in 3). To find x2, substitute the value you found for x1. x2 = 2 + 1/(2.333 333) = 2.428 571 Repeat this until you get an answer to a suitable degree of accuracy. This may be about the 5th value for an answer correct t
examples and worked solutions are shown.It is also possible to factorize trinomials without trial and error. This is shown in the last video on this page. We also have a trinomial calculator that will help you http://www.onlinemathlearning.com/factor-trinomials-unfoil.html to factorize trinomials. Use it to check your answers. Related Topics: More Algebra Lessons Example: Factor the following trinomial. x2 - 5x + 6 Solution: Step 1:The first term is x2, which is the product of x and x. Therefore, the first term in each bracket must be x, i.e. x2 - 5x + 6 = (x ... )(x ... ) Step 2: The last term is 6. The possible factors are ±1 and ±6 or ±2 trial and and ±3. So, we have the following choices. (x + 1)(x + 6) (x - 1)(x - 6) (x + 3)(x + 2) (x - 3 )(x - 2) The only pair of factors which gives -5x as the middle term is (x - 3)(x - 2) Step 3: The answer is then x2 - 5x + 6 = (x - 3 )(x - 2) Videos The following videos show many examples of factoring trinomial by the trial trial and error and error method.

It will also plot the graph. Factoring quadratics without trial and error This video shows a quick method for factoring quadratic expressions where the coefficient of the x squared term is not 1. This is a quick method that allows the correct answer to be achieved without trial and error and guess work.
