Question

simplify (3-√11) (3+√11) [2014]​

Answer 1

Answer:

(3-√11)(3+√11)

using (a-b)(a+b)= a²-b²

(3)²-(√11)²

9-11

-2

Answer 2

Answer:

-2

Step-by-step explanation:

(3-√11) (3+√11)

By Identity 3 ie:-

(a+b) (a-b) = a²-b²

Here , a= 3 and b = √11

So,

(3-√11) (3+√11) = 3² - (√11)²

(3-√11) (3+√11) = 9 - 11

{ because √11² = √121 = 11}

So, (3- √11) (3+√11) = -2

So, -2 is your answer....
