Question

If x is equal to 3 minus root under 2 if x is equal to 3 minus root under 2 find the value of x square + 1 divided by x square

Answer 1

Answer:

9/7

Step-by-step explanation:

x=3-√2

1/X= 1(3+√2)/(3-√2)(3+√2)

=3+√2/(3)square-(√2)square{(a+b)(a-b)=(a)square-(b)square}

=3+√2/9-2

=3+√2/7

Now,

(X+1/x)square=(3-√2)+(3+√2)/7

=3-√2+3+√2/7

=9/7
