Question

Simplify) : (5+2√6)-3 + (5-2/6 )-3​

Answer 1

4

Explanation:

(5+2√6)-3 + (5-2√6 )-3​ =

(5+2√6) + (5-2√6 )-3​-3 = ==> put like terms on one side

5+2√6 + 5-2√6 - 6 =

5+5 + 2√6 - 2√6 - 6 = ==> put like terms on one side

10 - 6 + 2√6 - 2√6 =

4 + 2√6 - 2√6 ===> simplify

4 + 0 = 4

Answer 2

4

Explanation:

Given expression:

`(5+2√(6))-3 + (5-2√(6))-3`

Remove the parentheses:

`\implies 5+2√(6)-3 + 5-2√(6)-3`

Collect like terms:

`\implies 5+ 5-3 -3+2√(6)-2√(6)`

Combine like terms:

`\implies 10-3 -3+2√(6)-2√(6)`

`\implies 7-3+2√(6)-2√(6)`

`\implies 4+2√(6)-2√(6)`

`\implies 4+0`

`\implies 4`
