Solving the Equation (x+5)(x-5) = 75
This equation presents a simple quadratic equation that we can solve using various methods. Let's break down the steps:
1. Expanding the Equation
The first step is to expand the left side of the equation using the difference of squares pattern:
(x+5)(x-5) = x² - 5²
This simplifies to:
x² - 25 = 75
2. Rearranging the Equation
Next, we move the constant term to the right side of the equation:
x² = 75 + 25
This gives us:
x² = 100
3. Solving for x
To find the value of x, we take the square root of both sides of the equation:
x = ±√100
This results in two possible solutions:
x = 10 or x = -10
Conclusion
Therefore, the solutions to the equation (x+5)(x-5) = 75 are x = 10 and x = -10.
