Quadratic, cubic and quartic equations Algebra index History Topics Index Version for printing It is often claimed that the Babylonians (about 400 BC) were the first to solve quadratic equations. This is an over simplification, for the Babylonians had no notion of 'equation'. What they did develop was an algorithmic approach to solving problems which, in our terminology, would give rise to a quadratic equation. The method is essentially one of completing the square. However all Babylonian problems had answers which were positive (more accurately unsigned) quantities since the usual answer was a length. In about 300 BC Euclid developed a geometrical approach which, although later mathematicians used it to solve quadratic equations, amounted to finding a length which in our notation was the root of a quadratic equation. Euclid had no notion of equation, coefficients etc. but worked with purely geometrical quantities. Hindu mathematicians took the Babylonian methods further so that Brahmagupta (598-665 AD) gives an, almost modern, method which admits negative quantities. He also used abbreviations for the unknown, usually the initial letter of a colour was used, and sometimes several different unknowns occur in a single problem. The Arabs did not know about the advances of the Hindus so they had neither negative quantities nor abbreviations for their unknowns. However

To cover the answer again, click "Refresh" ("Reload"). ax bx c The quadratic is on the left. is on the right. Question 2. What do we mean by a root of a quadratic? A solution to the quadratic equation. For example, this quadratic x x can be factored as x x Now, if x x = 2, the second factor will be 0. But if any factor is 0, then the entire product will be 0. That is, if x x x A root of a quadratic is also called a zero . Because, as we will see, at those values of x , the graph has the value 0. Question 3. How many roots has a quadratic? Always two. Question 4. What do we mean by a double root The two roots are equal. For example, this quadratic x x can be factored as x x If x = 5, then each factor will be 0, and therefore the quadratic will be 0. 5 is called a double root. A quadratic will have a double root if the quadratic is a perfect square trinomial Problem 1.

They then press the "calculate roots" button and the roots are given. If they then press the "try again" button, they are given a chance to do it again. Notes on the maths used in the applet: The roots of a quadratic equation (x1, x2), can be plotted on a graph. Negative quadratic equations (i.e -ax2 +bx +c = 0) gives a concave up curve and a positive equation gives a concave down curve. The applet uses the formula for calcualting roots to get the x values and prints these on the screen. Last updated: Thursday. May 03 2001

Printable Worksheets A quadratic equation is an equation that has a second-degree term and no higher terms. A second-degree term is a variable raised to the second power, like x . When you graph a quadratic equation, you get a parabola , and the solutions to the quadratic equation represent where the parabola crosses the x-axis. A quadratic equation can be written in the form: where a b , and c are numbers ( a ax + bx + c = Some examples of quadratic equations include: Solving a Quadratic Formula: Some quadratic equations can be solved easily by factoring. Some simple-to-solve quadratic equations are: x (x + 1)(x - 1) = x (x - 2)(x - 3) = x = 2, 3 Most second-degree equations are more difficult to solve, and cannot be solved by simple factoring. The quadratic formula is a general way of solving any quadratic equation: This formula gives two solutions, although the two solutions may be the same number.

Printable Worksheets Solving Quadratic Equations with No Linear Terms: There are many ways to solve quadratic equations. The easiest type of quadratic equations are in the form: ax - c = (having no linear term, that is, no x term). This type of equation is also called a pure quadratic equation and is easily solved by adding c tot each side, dividing each side by a, and then taking the square root of each side. For example: Some quadratic equations are slightly more complex, like ax + e = dx + d . This type of problem is also simple to solve. The first step is simplifying the equation by combining like terms (combine the squared terms and the numbers). The equation is then solved like the previous example (in math, problems are often solved by reducing them to a type of problem that you already know how to solve). For example: Go to Printable Worksheets on Quadratic Equations (with no linear term).

General Solving Solving by Factoring There are various methods for solving quadratics, none of which is terribly hard (with the notable exception of "completing the square"). Generally the greatest difficulty you will have is, given a quadratic on a test, knowing which method to use. So I will display each of the methods, and then will show you the reasoning you can go through to choose how to solve a given equation. You should already know how to factor quadratics. (If not, review Factoring Quadratics .) The new thing here is that the quadratic is part of an equation, and you're told to solve for the values of x that make the equation true. Here's how it works:
