Step-by-step solution
5 stepsTo find the range of values for that satisfy the inequality , we will follow these steps:
Move all terms to one side of the inequality to set it to zero.
Combine the terms into a single fraction by finding a common denominator.
The common denominator is .
Expand the numerator:
Distribute the negative sign:
Combine like terms in the numerator:
Factor the quadratic expression in the numerator.
The numerator can be factored as .
Identify the critical points where the numerator or denominator is zero.
These points divide the number line into intervals.
- From the numerator: and .
- From the denominator: . The critical points are .
Test a value from each interval created by the critical points to determine the sign of the expression .
- Interval 1: (e.g., test )
Since , this interval is part of the solution.
- Interval 2: (e.g., test )
Since , this interval is not part of the solution.
- Interval 3: (e.g., test )
Since , this interval is part of the solution.
- Interval 4: (e.g., test )
Since , this interval is not part of the solution.
The inequality is satisfied when the expression is negative.
Combining the intervals where the expression is negative gives the solution.The range of values for is:
