What Are the Solutions of the Equation X^4+95X^2-500?

Solving algebraic equations is a fundamental concept in mathematics, and often equations can have complex solutions. In this article, we will explore the solutions of the equation X^4+95X^2-500 and provide a step-by-step guide on how to find them. Additionally, we will include a frequently asked questions (FAQs) section to address common queries related to this equation.

Before we delve into the solutions, let us understand the equation itself. X^4+95X^2-500 is a fourth-degree polynomial equation, also known as a quartic equation. It involves both even and odd powers of the variable X, making it more challenging to solve compared to lower-degree equations. The goal is to find the values of X that satisfy this equation.

To solve the quartic equation X^4+95X^2-500, we need to follow a specific procedure. Here are the steps:

Step 1: Recognize the quartic equation format.

First, we identify that the equation is a quartic equation due to the presence of X^4 as the highest power of X.

Step 2: Make a substitution.

We can simplify the equation by making a substitution. Let Y = X^2, which transforms the quartic equation into a quadratic equation: Y^2 + 95Y – 500 = 0.

Step 3: Solve the quadratic equation.

Using the quadratic formula, we can find the values of Y that satisfy the quadratic equation Y^2 + 95Y – 500 = 0. The quadratic formula states that Y = (-b ± √(b^2 – 4ac))/(2a), where a, b, and c are the coefficients of the quadratic equation. In this case, a=1, b=95, and c=-500.

Step 4: Substitute back to find X.

Once we have found the values of Y, we substitute them back into the equation Y = X^2 to find the corresponding values of X.

After following these steps, we can find the solutions to the equation X^4+95X^2-500. In this case, we obtain four possible solutions for X.
