One of the main purposes of programs is to simplify often-performed tasks. In mathematics, these tasks often take the form of common and important equations---for example, the quadratic formula, used to find the roots or "zeroes" of a quadratic equation---the points where it crosses the x-axis. This article will show how to construct a TI-BASIC program that will do the quadratic formula, while illustrating a few of the program's key points. The formula is higher-level algebra, but this article won't go too in-depth mathematically. The quadratic formula can be used to solve quadratic equations, equations in the form ax2 + bx +c = 0. Remember that either 'b' and 'c' may be equal to zero, in which case the formula will be ax2 + bx or ax2 + c. If a = 0, the equation will be linear, which are solved differently. If c = 0, the equation is very simple to solve, as it will equal x(ax + b) = 0 in which case the solutions are x=0 and x=-b/a. (See Factorisation and simplification). The Quadratic Fomula is The Quadratic Formula is a mathematical formula used to find the x-intercepts for a quadratic function, or parabola. When With being the variable and , and being constant, the quadratic equation is: This is one possible method to determine the x-intercepts. They can also be found by completing the square, factoring or graphing. For the simpler formula where .
