0The quadratic formula can be derived by used a method called completing the square. It's like using algebra to solve for x. The process is explained the related link "Derivation of Quadratic Formula".

The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.

The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.

There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.

The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.

The question is based on the false assumption that the quadratic formula is not used in daily life. Wrong, it IS!

The quadratic formula is used all the time to solve quadratic equations, often when the factors are fractions or decimals but sometimes as the first choice of solving method. The quadratic formula is sometimes faster than completing the square or any other factoring methods. Quadratic formula find: -x-intercept -where the parabola cross the x-axis -roots -solutions

Using the quadratic equation formula is a method of solving quadratic equations.

When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.

Algebra can be used to solve for an unknown value in Graham's Law formula. The Grahams law formula can use algebra for solving for an unknown value in the formula.

The use of ax^2 + bx + c=0. This is the formula and can be best used to explain it. A,b, c stand for different numerical coefficients and you use factoring to solve the equation.

The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.

Algebra was first used in 1800 BC. There is evidence of the solution for quadratic elliptic equations in the Strasburg Tablet from Old Babylon.

The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?

The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.

quadratic formula is used often

To find the solutions of x in a quadratic equation.

Do you mean the quadratic formula? Not much; this would be more likely to be used by a scientist or engineer.

Probably the Babylonians because they were the first ones to used that formula around 700 BC.

Quadratic equations can be used in solving problems where the formula is given, falling object problems and problems involving geometric shapes.All types of engineering professions use the quadratic formula since it applies to ordinary differential equations.

-2x2 + 9x - 12 = 0Then apply the quadratic formula.

Physics problems, usually dealing with motion and acceleration.

In general, there are two steps in solving a given quadratic equation in standard form ax^2 + bx + c = 0. If a = 1, the process is much simpler. The first step is making sure that the equation can be factored? How? In general, it is hard to know in advance if a quadratic equation is factorable. I suggest that you use first the new Diagonal Sum Method to solve the equation. It is fast and convenient and can directly give the 2 roots in the form of 2 fractions. without having to factor the equation. If this method fails, then you can conclude that the equation is not factorable, and consequently, the quadratic formula must be used. See book titled:" New methods for solving quadratic equations and inequalities" (Trafford Publishing 2009) The second step is solving the equation by the quadratic formula. This book also introduces a new improved quadratic formula, that is easier to remember by relating the formula to the x-intercepts with the parabola graph of the quadratic function.

Finally, there are two methods to use, depending on if the given quadratic equation can be factored or not. 1.- The first one is the new Diagonal Sum Method, recently presented in book titled: "New methods for solving quadratic equations" (Trafford 2009). This method directly gives the two roots in the form of two fractions, without having to factor it. The innovative concept of this new method is finding 2 fractions knowing their product (c/a) and their sum (-b/a). This new method is applicable to any quadratic equation that can be factored. It can replace the existing trial-and-error factoring method since this last one contains too many more permutations. In general, it is hard to tell in advance if a given quadratic equation can be factored. However, if the new method fails to get the answers, then you can positively conclude that this equation can not be factored. Consequently, the quadratic formula must be used in solving. We advise students to always try to solve the given equation by the new method first. If the student gets conversant with this method, it usually take less than 2 trials to get answers. 2. the second one uses the quadratic formula that students can find in any algebra book. This formula must be used for all quadratic equations that can not be factored.

A corner where three edges meet is also called a vertex. A vertex can be also used in Algebra 2, in Quadratic Equations.
