Answer 2

Answer:

Hey mate ur Answer is here⤵

(x- root 2 )( x -root 2)

=( x - root 2)^2

= x^2 - 2.x . root 2 + root 2 ^2

= x^2 - 2root2x + 2

= x^2 - 2root2x -2root2x + 2 =0

= x( x - 2root2 ) - 2root2 ( x - 2root2 ) =0

= (x - 2root2 )( x - 2root2 ) = 0

= x = 2root2 Ans.

I HOPE IT HELPS U ✌ ✌ ✌ ✌
