To solve the equation x² - 1 = 0, you can follow these steps:
Step 1: Rearranging the Equation
First, you want to isolate the x² term. You can do this by adding 1 to both sides:
x² = 1
Step 2: Taking the Square Root
Next, take the square root of both sides. Remember that taking the square root can yield both positive and negative solutions:
x = ±√1
Step 3: Finding the Solutions
Since the square root of 1 is 1, you get:
- x = 1
- x = -1
Final Answer
The solutions to the equation x² - 1 = 0 are x = 1 and x = -1.
