Question

Simply this (3-√11)(3+√11)

Answer 1

Step-by-step explanation:

we have,(3-/11)(3+/11) {/=root}

(a-b)(a+b)

we know that (a-b)(a+b) =a2-b2

3^2-/11^2 =9-11= -2 ans.

Answer 2

Answer:

Here

(3-√11) (3+√11)

(3) ^2-(11) ^2

9-11

-2

Step-by-step explanation:

(a+b) (a-b) =a^2-b^2

remember this identity.
