Answer 3

To simplify the expression (5√5 - √12) • (2 - √5) + 7√3, follow these steps:

1. Simplify the square root of 12: √12 = √(4 * 3) = √4 * √3 = 2√3

2. Now, the expression becomes: (5√5 - 2√3) • (2 - √5) + 7√3

3. Apply the distributive property (FOIL) to the two binomials: = (5√5 * 2 - 5√5 * √5 - 2√3 * 2 + 2√3 * √5) + 7√3

4. Multiply the terms: = (10√5 - 5√25 - 4√3 + 2√15) + 7√3

5. Simplify further: = (10√5 - 5√25 is -√25 which is -5√5) = (-5√5 - 4√3 + 2√15) + 7√3

6. Combine like terms: = -5√5 - 4√3 + 2√15 + 7√3

7. Combine the √3 terms and the √5 terms separately: = (-4√3 + 7√3) + (-5√5 + 2√15)

8. Simplify: = 3√3 - 5√5 + 2√15

So, the simplified expression is: 3√3 - 5√5 + 2√15
