Answer 2

Let's simplify the given expression step-by-step:

1. Start with the expression: (√17 + 2)^2 - 4√17

2. Square the term (√17 + 2): (√17 + 2)^2 = (√17 + 2) * (√17 + 2) = (√17)^2 + 2 * √17 * 2 + 2^2 = 17 + 4√17 + 4 = 21 + 4√17

3. Substitute the squared term back into the original expression: (√17 + 2)^2 - 4√17 = (21 + 4√17) - 4√17

4. Simplify the expression by combining like terms: (21 + 4√17) - 4√17 = 21

So, the simplified expression is 21.
