Answer 2

Step-by-step explanation:

5 - √10 - 5 + √10

5 + √10 5 - √10

To subtract first we have to make the denominator same. To make the denominator same we have to multiþly the denominator by each other.

(5-√10)*(5-√10) - (5+√10)*(5+√10)

(5-√10)*(5+√10) (5-√10)*(5+√10)

(5-√10)² - (5+√10)²

(5)²-(√10)² (5)²-(√10)²

5²+(√10)²-(2*5*√10) - 5²+(√10)²+(2*5*√10)

25 - 10 25 - 10

25+10-10√10 - 25+10+10√10

15 15

(35 - 10√10) - (35 + 10√10)

15

35 - 10√10 - 35 - 10√10

15

-10√10 - 10√10

15

-20√10 (-20 & 15 can be divided by 5)

15

-4√10
