Question

Simplify of the (3+√3) (3-√3) expressions​

Answer 1

Answer:

in this sum we use this identity (a+b)(a-b)=a²-b²

(3+√3)(3-√3)=(3)²-(√3)²

=9-3

=6

Answer 2

Step-by-step explanation:

Given,

to simplify following expression,

(3+√3)(3-√3)

As we know that (a+b)( a-b) = a²-b²

Here a = 3 and b = √3

so, (3+√3) (3-√3)

= (3)² - (√3)²

= 9-3

= 6

hence, (3+√3) (3-√3) = 6
