Understanding the Value of x in Complex Square Root Equations

In the realm of algebra, understanding how to solve complex square root equations can be both challenging and rewarding. One notable example is the equation {√x2144} ÷ √x-5 √x5 17 ÷ {√x-5}. This equation involves multiple layers of square roots, making it a valuable case study for enhancing one’s problem-solving skills.

Step-by-Step Solution

To solve the given equation, we will follow a systematic approach, breaking it down into simpler steps:

Multiplication by the Conjugate: Begin by multiplying both sides of the equation by the conjugate of the denominator, x-5, to simplify the fraction. Eliminating the Denominator: This results in the equation x2144(x2-25) 17(x-5). Simplifying the Equation: Further simplification leads to the form x2144 17 - x2-25, which can be further simplified as x2144 289 - x2-25 - 34x2-25. Reorganizing Terms: Reorganize the terms to get a clearer view: x2144 289 - 34x2-25. Squaring Both Sides: Square both sides of the equation to remove the square root, which simplifies to x 6.1202 or x -6.1202.
