Solving the Equation (x-4)² = 169
This equation involves a squared term, which means we need to use the square root property to solve for x. Here's a step-by-step guide:
1. Isolate the squared term
The squared term is already isolated on the left side of the equation: (x - 4)² = 169
2. Take the square root of both sides
Remember that taking the square root of a number can result in both positive and negative values.
√(x - 4)² = ±√169
3. Simplify
This simplifies to:
x - 4 = ±13
4. Solve for x
We have two possible solutions:
-
Case 1: x - 4 = 13 Adding 4 to both sides, we get: x = 17
-
Case 2: x - 4 = -13 Adding 4 to both sides, we get: x = -9
