Solving Inequalities: A Comprehensive Guide for SEO

In mathematics, solving inequalities is a crucial skill that helps us find the range of values that satisfy a given condition. This article aims to provide a detailed, step-by-step guide on solving inequalities, along with practical SEO tips for improving visibility on search engines like Google. By understanding and mastering these concepts, you can not only solve complex math problems but also enhance your online presence through effective SEO techniques.

Understanding Inequalities and Their Importance

Before diving into the specifics of solving inequalities, it's essential to grasp the concept itself. An inequality is a statement that compares two expressions using symbols such as , , ≤, or ≥. Solving an inequality means finding all the values of the variable that make the inequality true. This concept is fundamental in various fields, including algebra, calculus, and real-world applications like economics and engineering.

Step-by-Step Guide to Solving Inequalities

Let's explore the step-by-step process of solving inequalities using a specific example. We will solve the inequality:

Determine the inequality:

D: 1/(x-2) - 1/(x^2)

We need to solve for x in the inequality 1/(x-2)

Step 1: Find a common denominator

Start by finding a common denominator to combine the fractions. In this case, the common denominator is x^2(x-2).

LHS: 1/(x-2) x^2/(x^2(x-2)), RHS: 1/(x^2) (x-2)/ (x^2(x-2))

Step 2: Combine the fractions

Now, we can rewrite the inequality as:

x^2/(x^2(x-2))

Subtracting the right-hand side from the left gives:

x^2 - (x-2)

Step 3: Simplify the inequality

Expanding and simplifying the expression:

x^2 - x 2

Step 4: Solve the quadratic inequality

Now, let's solve the quadratic inequality x^2 - x 2

The discriminant of the quadratic equation is:

Δ b^2 - 4ac (-1)^2 - 4(1)(2) 1 - 8 -7

Since the discriminant Δ

Given that the coefficient of x^2 is positive (1), the parabola opens upwards, and the inequality x^2 - x 2

Step 5: Determine the intervals where the inequality is true

The next step involves determining where the expression x^2 - x 2

1. The denominator (x-2) must not be zero, so x ≠ 2.

2. The denominator (x^2) must not be zero, so x ≠ 0.

The critical points are x 0 and x 2. We test the intervals: (-∞, 0), (0, 2), and (2, ∞).

- For x in (-∞, 0): Choose x -1, then (1/(-1-2)) - (1/((-1)^2))

- For x in (0, 2): Choose x 1, then (1/(1-2)) - (1/(1^2))

- For x in (2, ∞): Choose x 3, then (1/(3-2)) - (1/(3^2))

The solution is the interval (0, 2).
