Math Problem Statement

Solve the inequality |x - 2| < 12 algebraically.

Solution

To solve the inequality algebraically:

x2<12|x - 2| < 12

Step 1: Understand the property of absolute value inequality

For a<b|a| < b, this implies: b<a<b-b < a < b

Step 2: Apply this property to the given inequality

Here, a=x2a = x - 2 and b=12b = 12. Therefore: 12<x2<12-12 < x - 2 < 12

Step 3: Solve for xx

Add 22 to all parts of the inequality: 12+2<x2+2<12+2-12 + 2 < x - 2 + 2 < 12 + 2 10<x<14-10 < x < 14

Final Answer:

The solution to the inequality is: x(10,14)x \in (-10, 14)

Would you like further explanations or a graphical representation of this solution?
