Question

if x = 2 + root 3 then find X square + 1 upon x square​

Answer 1

Answer:

Step-by-step explanation:

x = 2 + root 3

squaring it

x^2=7+4root3

now 1/x^2=1/(7+4root3)

rationalize it i.e multiply by 7-4root3 in num. and den.

in den.  (7-4root3)(7+4root3)=1

you will get 1/x^2=7-4root3

adding both X square + 1 upon x square​

=7+4root3+7-4root3=14
