如何计算Absolute Value Equation Solver
learn.whatIsHeading
Absolute value equations describe the distance of a number from zero on a number line. Solving |x - a| = b requires considering both positive and negative cases, as distance is always non-negative.
公式
|x - a| = b → x - a = b or x - a = -b
分步指南
- 1Set up two equations: positive and negative cases
- 2Solve each equation separately
- 3Verify both solutions in the original equation
例题解析
输入
|x - 3| = 5
结果
x = 8 or x = -2
Both values are 5 units away from 3
常见错误注意事项
- ✕Forgetting the negative case
- ✕Not checking solutions in the original equation
