The problem shown in the image appears to be:

Expand and simplify:
$(2 - 2\sqrt{5}) + (5 + \sqrt{5})$

Step 1: Combine like terms

• Combine the constant terms: $2 + 5 = 7$
• Combine the terms with $\sqrt{5}$: $-2\sqrt{5} + \sqrt{5} = -\sqrt{5}$

Step 2: Write the simplified expression

The result is: $7 - \sqrt{5}$
