Question

9. If x = 3 - 2/2, find the value of x2+ 1 divided by x2​

Answer 1

Answer:

3-1=2 so x=2

your answer is 5/4

Answer 2

Step-by-step explanation:

x = 3-2√2

x2 = (3-2√2)2 = 9+8-12√2 = 17-12√2

1/x2= 1/17-12√2

Rationalise The Denominator

1*17+12√2 / (17-12√2 ) * (17+12√2) = 17+12√2/289-288 = 17+12√2

Now Add We Get

17-12√2+17+12√2 = 34
