Earliest method used to solve quadratic equation

Earliest Methods used to solve Quadratic Equation 1. Babylonian mathematics also known as Assyro-Babylonian mathematics was any mathematics developed or practiced by the people of Mesopotamia, from the days of the early Sumerians to the fall of Babylon in BC.

Quadratic, cubic and quartic equations. It is often claimed that the Babylonians about 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.

The numbers a , b , and c are the coefficients of the equation and may be distinguished by respectively calling them, the quadratic coefficient , the linear coefficient and the constant coefficient or free term. The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side. A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root. If all the coefficients are real numbers , there are either two real solutions, or a single real double root, or two complex solutions that are complex conjugates of each other. A quadratic equation always has two roots, if complex roots are included; and a double root is counted for two. Completing the square is one of several ways for deriving the formula. Solutions to problems that can be expressed in terms of quadratic equations were known as early as BC. Because the quadratic equation involves only one unknown, it is called " univariate ". The quadratic equation contains only powers of x that are non-negative integers, and therefore it is a polynomial equation. In particular, it is a second-degree polynomial equation, since the greatest power is two. A quadratic equation with real or complex coefficients has two solutions, called roots. These two solutions may or may not be distinct, and they may or may not be real. In some cases, it is possible, by simple inspection, to determine values of p , q , r, and s that make the two forms equivalent to one another. Solving these two linear equations provides the roots of the quadratic.

In some fields, some elements have no square roots and some have two; only zero has just one square root, except in fields of characteristic 2. Isoperimetric problems and the origin of the quadratic equations, Isis 32-

Quadratic equations come up often in mathematics and physics, and it is vital to know how to solve them. Luckily, there are several ways to do it. So, how do you solve quadratic equations? Graphing gives a good visual, but it is hard to find values of x from a graph with no equation. If factoring is hard, the quadratic formula a shortcut for completing the square helps. Of course, the quadratic formula will work for any quadratic equation you choose. However, it might be easier to factor in some cases to avoid radicals and fractions in the quadratic formula. Here are four methods you can use to solve a quadratic equation :. To solve a quadratic equation by graphing, all we really need to do is find out where the zeros are the points where the graph intersects the x-axis.

There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. Setting each factor to zero,. Then to check,. Setting each factor to 0,. A quadratic with a term missing is called an incomplete quadratic as long as the ax 2 term isn't missing. Many quadratic equations cannot be solved by factoring. This is generally true when the roots, or answers, are not rational numbers.

For functions defined by polynomials of degree two, see Quadratic function. There has been debate over the earliest appearance of Babylonian mathematics, with historians suggesting a range of dates between the 5th and 3rd millennia BC. In other projects. Later the characteristic of those line, space of geometrical shape was given intense study and utilized sophisticated geometry in designing waterwheels, in improving farming equipment, in developing new type of weapon used at war. In his work, al-Khwarizmi explains the principles of solving linear and quadratic equations, the concept that an equation can be created to find the value of an unknown variable. The location and size of the parabola, and how it opens, depend on the values of a , b , and c. The earliest methods for solving quadratic equations were geometric. The quadratic formula covering all cases was first obtained by Simon Stevin in Rebolusyong siyentipiko mrRAYdiation. B Hughes, The earliest correct algebraic solutions of cubic equations, Vita mathematica Washington, DC, , -

When we solved quadratic equations in the last section by completing the square, we took the same steps every time. Mathematicians look for patterns when they do things over and over in order to make their work easier.

The figure shows the difference between [ clarification needed ] i a direct evaluation using the quadratic formula accurate when the roots are near each other in value and ii an evaluation based upon the above approximation of Vieta's formulas accurate when the roots are widely spaced. Other ways of solving a quadratic equation, such as completing the square , yield the same solutions. S2CID Babylonians, as a whole, were intelligent people, good soldiers, keen traders, and very skillful craftsmen Cottrell, Page His solution of the quadratic equation was as follows: "To the absolute number multiplied by four times the [coefficient of the] square, add the square of the [coefficient of the] middle term; the square root of the same, less the [coefficient of the] middle term, being divided by twice the [coefficient of the] square is the value.
