Answer:

             Q. ( 2 - √3 ) ( 2 + √3 )

solution :   using the algebraic identity

                  ⇒( a + b ) ( a - b ) = a² - b²

                  ⇒ a = 2

                  ⇒ b = √3

                  ⇒ ( 2 - √3 ) ( 2 + √3 )

                  ⇒ ( 2 )² - ( √3 )²  

                  ⇒  4 - 3

                  ⇒  1

  Hence your answer is  1
