Understanding the Basics of X 2 5X

Before diving into the solutions, it's essential to grasp the basics of X 2 5X. This expression is a quadratic equation in the form of ax² + bx + c = 0, where a = 1, b = -5, and c = 0. The general form of a quadratic equation is:

ax² + bx + c = 0

In the case of X 2 5X, the equation simplifies to:

x² - 5x = 0

This equation can be solved using various methods, including factoring, completing the square, and using the quadratic formula. Each method has its advantages and is suitable for different scenarios.

Solving X 2 5X Using Factoring

Factoring is one of the simplest methods to solve X 2 5X. The goal is to find two numbers that multiply to give the constant term (which is 0 in this case) and add up to give the coefficient of the x term (-5).

Let's factor X 2 5X:

x² - 5x = 0

We can factor out an x from both terms:

x(x - 5) = 0

Setting each factor equal to zero gives us the solutions:

x = 0 or x = 5

Thus, the solutions to the equation X 2 5X are x = 0 and x = 5.

📝 Note: Factoring is a straightforward method when the quadratic equation can be easily factored. However, it may not always be applicable, especially for equations with non-integer coefficients.

Solving X 2 5X Using the Quadratic Formula

The quadratic formula is a universal method to solve any quadratic equation. The formula is given by:

x = [-b ± √(b² - 4ac)] / (2a)

For the equation X 2 5X, we have a = 1, b = -5, and c = 0. Plugging these values into the formula, we get:

x = [-(-5) ± √((-5)² - 4(1)(0))] / (2(1))

x = [5 ± √(25 - 0)] / 2

x = [5 ± √25] / 2

x = [5 ± 5] / 2

This gives us two solutions:

x = (5 + 5) / 2 = 10 / 2 = 5

x = (5 - 5) / 2 = 0 / 2 = 0

Thus, the solutions are x = 5 and x = 0, which match the solutions obtained through factoring.

📝 Note: The quadratic formula is particularly useful when factoring is not straightforward or when dealing with equations that have non-integer coefficients.
