Solving Complex Equations and Understanding Fractions: A Comprehensive Guide for SEO

Introduction:

Understanding and solving complex equations is a crucial skill in mathematics, essential for various fields such as engineering, physics, and even digital marketing. This guide focuses on a specific problem: solving the quadratic equation (x^2 - 7x 1 0) and then utilizing the result in a more intricate expression. The techniques and strategies explained here will not only help in finding the solution but also enhance SEO optimization through better content and structure.

The Problem and Its Solution

We start with the given equation: (x^2 - 7x 1 0). To find the value of (x), we use the quadratic formula:

(x frac{-b pm sqrt{b^2 - 4ac}}{2a})

In our case, the coefficients are:

(a 1) (b -7) (c 1)

Substituting these values into the formula, we get:

(x frac{7 pm sqrt{(-7)^2 - 4 cdot 1 cdot 1}}{2 cdot 1} frac{7 pm sqrt{49 - 4}}{2} frac{7 pm sqrt{45}}{2} frac{7 pm 3sqrt{5}}{2})

This gives us two possible values for (x): (x_1 frac{7 3sqrt{5}}{2}) (x_2 frac{7 - 3sqrt{5}}{2})

Next, we need to compute (x cdot frac{1}{x} - 7).

Algebraic Manipulation

1. Finding (frac{1}{x}):

To find (frac{1}{x}), we use the values of (x) we just computed:

(frac{1}{x} frac{2}{7 pm 3sqrt{5}})

We simplify this by multiplying the numerator and denominator by the conjugate:

(frac{1}{x} frac{7 mp 3sqrt{5}}{49 - 45} frac{7 mp 3sqrt{5}}{4} frac{7 mp 3sqrt{5}}{2})

2. Computing (x cdot frac{1}{x}):

Now we compute:

(x cdot frac{1}{x} frac{7 pm 3sqrt{5}}{2} cdot frac{7 mp 3sqrt{5}}{2} frac{49 - 45}{4} 7)

3. Final Calculation:

Substituting this result into the original expression:

(x cdot frac{1}{x} - 7 7 - 7 0)

Therefore, the final answer is 0.
