It seems the OCR (Optical Character Recognition) process did not successfully extract the text from the image due to its quality or formatting. Let me manually interpret the expression and solve it.

The mathematical expression in the image appears to be: $\left(\frac{2\sin\frac{\pi}{2} - m}{2}\right) - \left(\frac{\pi^2 - \pi^2 + 4}{\pi^2 + 4}\right) \times \left(\frac{2\pi}{2 + 2}\right) - \left(\frac{2\sin\frac{\pi}{2} - m}{2}\right)$

Let's break it down and solve it step by step.The simplified form of the given expression is:

$-\frac{2\pi}{4 + \pi^2}$

This is the final simplified result. Let me know if you have any questions or need further explanation.
