Math Problem Statement
How to place equations somewhere? Like y^2<y but i want to place this to -2! How to do it?
Solution
To place the inequality into a position where it holds true, such as around , you need to check if satisfies the inequality. Here's how you do it:
-
Start with the inequality:
-
Substitute into the inequality:
-
Simplify both sides:
Since is not less than , the inequality does not hold true at .
To find where the inequality holds, let's analyze it further:
-
Rearrange the inequality:
-
Factor the expression:
This inequality holds where the product is negative, which occurs between the roots and . Thus, must lie in the interval .
Steps Summary:
- Check if a specific value like satisfies the inequality by substituting and simplifying.
- Analyze and factor the inequality to find the range of where the inequality holds.
