Answer 2

To simplify the expression (3√2 - √5) * (√5 + 3√2), we can use the distributive property of multiplication. The expression can be simplified as follows:

(3√2 - √5) * (√5 + 3√2) = 3√2 * √5 + 3√2 * 3√2 - √5 * √5 - √5 * 3√2 = 3√(25) + 3√(2^2) - √(5^2) - √(52) = 3√10 + 3√4 - √25 - √10 = 3√10 + 3*2 - 5 - √10 = 3√10 + 6 - 5 - √10 = 3√10 + 1 - √10

So, the simplified expression is 3√10 + 1 - √10.
