Solving the Equation (x+8)² - 2 = 0
This article will guide you through the process of solving the quadratic equation (x+8)² - 2 = 0.
Understanding the Equation
The equation represents a quadratic expression, which is a polynomial with the highest power of the variable being 2. To solve this, we need to find the values of x that satisfy the equation.
Steps to Solve the Equation
-
Isolate the squared term:
- Add 2 to both sides of the equation: (x+8)² = 2
-
Take the square root of both sides:
- Remember to consider both positive and negative roots: x + 8 = ±√2
-
Solve for x:
- Subtract 8 from both sides: x = -8 ±√2
Solutions
Therefore, the solutions to the equation (x+8)² - 2 = 0 are:
- x = -8 + √2
- x = -8 - √2
Conclusion
By following these steps, we have successfully solved the quadratic equation (x+8)² - 2 = 0 and obtained its two solutions. This method can be applied to solve other quadratic equations in a similar manner.
