Final answer:
The algebraic expression described can be written as y²/x > 2, which can be manipulated using algebraic techniques like cross-multiplication and solving quadratic equations when necessary.
Step-by-step explanation:
The question appears to describe an expression where y squared (y²) is being divided by x, and the result is greater than 2. The algebraic expression representing this would be y²/x > 2. This condition can be rearranged and solved using various algebraic techniques such as cross-multiplication and solving quadratic equations when necessary.
If further simplification or solving is required, such as when x² is part of the expression, techniques like completing the square or the quadratic formula can be employed. For instance, if we encounter an expression of the form x², and it's part of an inequality or equation, we would aim to simplify or manipulate the expression so that it's in a more solvable form, such as a perfect square.
