In summary, an equation at the third and more, also known as a polynomial equation, is an algebraic expression that contains variables raised to powers greater than or equal to three. To solve equations at the third and more, you can use various techniques such as factoring, completing the square, or using the quadratic formula. These equations can have multiple solutions, determined by the degree of the equation. The main difference between a quadratic equation and an equation at the third and more is the degree, with the latter being more complex to solve. Equations at the third and more have various real-world applications in fields such as physics, engineering, economics, and cryptography.

Equations that have x^3 or x^4 etc...,are solved with method of Horner.
There is quicker way to solve an equation like that? (except factorization).

Thank you a lot!

Well, there's a general formula for solving cubic and quartic equations. However, Abel's impossibility theorem states that there cannot be explicit algebraic formulas for the general solutions to degree 5 and higher polynomials.

But some techniques can help you solve such equations...

For example, this page discuss the solvability of quintic equations: http://library.wolfram.com/examples/quintic/
 

FAQ: Equations at the third and more.

1. What is an equation at the third and more?

An equation at the third and more, also known as a polynomial equation, is an algebraic expression that contains variables raised to powers greater than or equal to three. It typically takes the form of ax^3 + bx^2 + cx + d = 0, where a, b, c, and d are constants.

2. How do you solve equations at the third and more?

To solve equations at the third and more, you can use various techniques such as factoring, completing the square, or using the quadratic formula. These methods involve manipulating the equation to get all the variable terms on one side and the constants on the other side, and then solving for the variable.

3. Can equations at the third and more have multiple solutions?

Yes, equations at the third and more can have multiple solutions. The number of solutions is determined by the degree of the equation, which is the highest power of the variable. For example, a third-degree equation can have up to three solutions, while a fourth-degree equation can have up to four solutions.

4. What is the difference between a quadratic equation and an equation at the third and more?

The main difference between a quadratic equation and an equation at the third and more is the degree of the equation. A quadratic equation has a degree of two, meaning it contains variables raised to powers of two or less, while an equation at the third and more has a degree of three or higher. As a result, solving equations at the third and more can be more complex and involve using more advanced techniques.

5. What are some real-world applications of equations at the third and more?

Equations at the third and more have various real-world applications in fields such as physics, engineering, and economics. For example, they can be used to model the motion of objects under the influence of gravity, calculate the optimal production level of a product, or predict the behavior of stock prices. They are also used in cryptography to create secure codes and algorithms.
