Introduction

In mathematics, solving equations is a fundamental concept that helps us understand various mathematical concepts and their applications. One such equation is the quartic equation, which is a polynomial equation of degree four. In this article, we will focus on solving the quartic equation x4+x=0x^4 + x = 0. This equation may seem simple, but it requires careful analysis and application of mathematical techniques to find its solutions.

Understanding the Quartic Equation

The quartic equation x4+x=0x^4 + x = 0 is a polynomial equation of degree four, where the highest power of the variable xx is four. This equation can be rewritten as x4+x−0=0x^4 + x - 0 = 0, which is a standard form of a polynomial equation. The equation has two terms: x4x^4 and xx, which are added together to form the equation.

Factoring the Quartic Equation

To solve the quartic equation x4+x=0x^4 + x = 0, we can start by factoring the equation. Factoring involves expressing the equation as a product of simpler equations. In this case, we can factor out the common term xx from both terms:

x4+x=x(x3+1)=0x^4 + x = x(x^3 + 1) = 0

This gives us two factors: xx and (x3+1)(x^3 + 1). We can set each factor equal to zero to find the solutions:

x=0x = 0 or x3+1=0x^3 + 1 = 0

Solving the Cubic Equation

Now, we need to solve the cubic equation x3+1=0x^3 + 1 = 0. This equation can be rewritten as x3=−1x^3 = -1. To solve this equation, we can use the cube root property, which states that if x3=ax^3 = a, then x=a3x = \sqrt[3]{a}.

x=−13x = \sqrt[3]{-1}

Simplifying the Cube Root

The cube root of −1-1 can be simplified using the properties of complex numbers. The cube root of −1-1 is a complex number that can be expressed as:

x=−1x = -1

Finding the Solutions

Now, we have found the solutions to the quartic equation x4+x=0x^4 + x = 0. The solutions are:

x=0x = 0 or x=−1x = -1

Conclusion

In this article, we have solved the quartic equation x4+x=0x^4 + x = 0 using factoring and the cube root property. We have found the solutions to the equation, which are x=0x = 0 and x=−1x = -1. This equation may seem simple, but it requires careful analysis and application of mathematical techniques to find its solutions.
