Solving the Equation: (x+2)^2 - 3 = 1
This article will walk through the steps involved in solving the equation (x+2)^2 - 3 = 1.
Step 1: Isolate the Squared Term
- Add 3 to both sides of the equation: (x+2)^2 - 3 + 3 = 1 + 3
- Simplify: (x+2)^2 = 4
Step 2: Take the Square Root of Both Sides
- Apply the square root operation to both sides: √[(x+2)^2] = ±√4
- Simplify: x + 2 = ±2
Step 3: Solve for x
- Isolate x by subtracting 2 from both sides: x + 2 - 2 = ±2 - 2
- Simplify: x = -2 ± 2
Step 4: Calculate the Solutions
- Calculate the positive solution: x = -2 + 2 = 0
- Calculate the negative solution: x = -2 - 2 = -4
Conclusion
Therefore, the solutions to the equation (x+2)^2 - 3 = 1 are x = 0 and x = -4.
