Solving Quadratic Equations (at the Algebra 1 level) Find the solutions (roots) of a quadratic equation using the graphing calculator. Consider the following examples: Using the ZERO Command Solve: Since this equation is set equal to zero, the roots will be the locations where the graph crosses the x -axis (if the roots are real numbers). (Remember that the x -axis is really just y 1. Set 2. Use the ZERO command to find the roots 2nd TRACE (CALC), #2 zero Left bound? Move the spider as close to the root (where the graph crosses the x- axis) as possible. Hit the left arrow to move to the "left" of the root. Hit ENTER. A "marker" will be set to the left of the root. Right bound? Move the spider as close to the root (where the graph crosses the x- axis) as possible. Hit the right arrow to move to the "right" of the root. Hit ENTER. A "marker" will be set to the right of the root.

Quadratic equation From Wikipedia, the free encyclopedia Jump to: navigation search This article is about quadratic equations and solutions. For more general information about quadratic functions, see Quadratic function . For more information about quadratic polynomials, see Quadratic polynomial In mathematics , a quadratic equation is a polynomial equation of the second degree . The general form is where x represents a variable , and a b , and c constants , with a ≠ 0. (If a = 0, the equation becomes a linear equation The constants a b , and c , are called respectively, the quadratic coefficient , the linear coefficient and the constant term or free term. The term "quadratic" comes from quadratus , which is the Latin word for " square ". Quadratic equations can be solved by factoring completing the square graphing Newton's method , and using the quadratic formula (given below). One common use of quadratic equations is computing trajectories in projectile motion . Another common use is in electronic amplifier design for control of step response and stability Plots of real -valued quadratic function ax bx c , varying each coefficient separately Contents Quadratic formula Discriminant Geometry Quadratic factorization ... edit Quadratic formula A quadratic equation with real or complex coefficients has two solutions, called

Horizontal and Vertical Lines Solving Quadratic Equations Quadratic Equation in One Variable: ax + bx + c = 0, where a, b and c are real numbers with a 0. We will solve these equations by several methods. I. Solving Quadratic Equations by Factoring The Zero Product Property: ab = if and only if either a = or b = or both a and b equal zero. II. Graphical Solution Once the equation is written in the form ax + bx + c = 0, we can graph the left side as y and find the x- intercepts. These x-intercepts or zeros of the function are the solutions to the quadratic equation ax + bx + c = 0. III. Square Root Property The solution set of x = k is: IV. Using the Quadratic Formula to Solve Quadratic Equations If ax + bx + c = 0, a 0, then: b - 4ac is called the discriminant of the quadratic equation.

If it can be factored, there is a new method, called the Diagonal Sum Method, that can quickly give the 2 roots in the form of 2 fractions. The concept of this method is finding 2 fractions, knowing their Sum (-b/a) and their Product (c/a). It is faster and more convenient than the trial-and-error factoring method since it works with fewer permutations, and it is always applicable whenever the equation can be factored. abu sheriff says: October 8, 2010 at 11:11 am it is good Leave a Reply Click here to cancel reply.

Here's what they're saying: Your program so far has been great. I purchased this software for my 13 yr. old daughter who is having some problems in math. We have a tutor coming over to the house and between your software and him she got her first "A" in a very hard chapter test. As you might know sometimes when you see a different approach on a problem or sometimes just someone else showing you different ways to understand the problem that is all it takes. Your software seems to give this problem solving approach in a way that is easy to understand. Thanks again, the whole Turley family. Walt Turley, Long Beach, CA I bought "The Algebrator" for my daughter to help her with her 10th Grade Advanced Algebra class. Like most kids, she was getting impatient with the evolution of equations (quadratic in particular) and making mistakes in her arithmetic. I very much like the step-by-step display of your product. I think it got my daughter a better grade in the past semester. Tom Canty, Phoenix, AZ

39. QUADRATIC EQUATIONS,algebra From A-level Maths Tutor All quadratic equations have two roots/solutions.Here you will find methods of finding these roots by factorising,completing the square and using the formula. http://a-levelmathstutor.com/quadratic-eq.php

Algebra : Quadratic Equations factorising completing the square using the formula a drop-down menu of resources for 'empty.' empty: coming soon Introduction The general form of a quadratic equation is: a x +b x + c where a b c are constants The expression b is called the discriminant and given the letter (delta). All quadratic equations have two roots/solutions. These roots are either REAL EQUAL or COMPLEX complex - involving the square root of -1 back to top Solution by factorising - This is best understood with an example. solve: You must first ask yourself which two factors when multiplied will give The factor pairs of are : 1 x 12 2 x 6 and 3 x 4 You must decide which of these factor pairs added or subtracted will give 1 : 12 ...gives 13, 11 2 : 6 .....gives 8, 4 3 : 4 .....gives 7, 1 Which combination when multiplied makes +12 and which when added gives -7? these are the choices: Clearly, (-3)(-4) are the two factors we want. therefore Now to solve the equation factorising, as above either or for the equation to be true. So the roots of the equation are: back to top Completing the square This can be fraught with difficulty, especially if you only half understand what you are doing.
