Question

find the zeros of the polynomial x squared minus 3

Answer 1

Given equation :- x² - 3

3 can be written as the product of
√3 ×√3
as square of √3

forming the identity that is :-

a² - b² = ( a + b ) ( a - b )

= > x² - ( √3 )²

( x + √3 ) ( x - √3 )

* ( x + √3 ) = 0
x = - √3

* ( x - √3 ) = 0
x = √3

Answer 2

x² - 3

x² - ( √3 )²

used Identity :- a² - b² = ( a + b ) ( a - b )

( x + √3 ) ( x - √3 )

° ( x + √3 ) = 0
x = - √3

° ( x - √3 ) = 0
x = √3
