1.	12If x= 3 +2√2, find the value of x^2+1/x^2
Answer» Step-by-step EXPLANATION: x = 3 + 2root2 then 1/x= 1/3+2root2 =3 - 2root2/9-8= 3-2root2 and we know that (x+1/x)"2=x^2 + 1/x^2 +2 putting VALUE of x and 1/x we get 36=req value +2 which IMPLIES that your ANSWER is 34. Plz mark me as the BRAINLIEST!!

Answer»

Step-by-step EXPLANATION:

x = 3 + 2root2

then 1/x= 1/3+2root2

=3 - 2root2/9-8= 3-2root2

and we know that (x+1/x)"2=x^2 + 1/x^2 +2

putting VALUE of x and 1/x

we get 36=req value +2

which IMPLIES that your ANSWER is 34.

Plz mark me as the BRAINLIEST!!
