Question

If X = 1 + √2 find the value of x² + 1/ X² solve it fast I will mark u as brainlest

Answer 1

Answer:

1/x^2 =  1 / 1 + root 2

= 1(1- root 2) / (1+ root 2 )(1- root 2)

 = (1-root2)/ ( 1 )^2 - (root 2)^2

= (1-root 2 )/1-2

= (1-root 2)/-1

= -(1-root 2)

= -1+root2

x^2+1/x^2  = 1+root 2-1+root  =√4
