The image you've uploaded contains the following mathematical inequality:

Let $x$ and $y$ be non-negative real numbers. The inequality is given as:

$\frac{x}{2} \geq \sqrt{xy + y}$

This inequality seems to relate to certain properties of real numbers and might involve algebraic manipulation or the application of specific inequalities like the Arithmetic-Geometric Mean Inequality (AM-GM inequality). Let's break this down and check for any valid proof.

Step-by-step Analysis:

1. Squaring Both Sides: Since $x$ and $y$ are non-negative, we can safely square both sides of the inequality without reversing it:

$\left( \frac{x}{2} \right)^2 \geq \left( \sqrt{xy + y} \right)^2$

This simplifies to:

$\frac{x^2}{4} \geq xy + y$

2. Rearranging Terms: Bring all terms to one side:

$\frac{x^2}{4} - xy - y \geq 0$

Multiply through by 4 to eliminate the denominator:

$x^2 - 4xy - 4y \geq 0$

3. Factoring (if possible): We now analyze this quadratic inequality in terms of $x$ and $y$. This is where further algebraic manipulation or specific conditions on $x$ and $y$ might simplify the inequality.
