Question

if X equals to 2 minus root 3 find X square + 1 by x square​

Answer 1

x=2-√3

x^2 = (2-√3)^2

=4-4√3+3 = 7-4√3

x^2+1 = 7-4√3+1 = 8-4√3

(x^2+1)/x^2 = (8-4√3)/(7-4√3)

Answer 2

Step-by-step explanation:

The value of X given is : 2-√3

and we have Equation given as : X²+1/X²

so put value of x in equation,

(2-√3)²+1/(2-√3)²

4-3+1/4-3 ∴[Remember that when we multiply (√) by 2 times it get cancelled].

1+1/1

2.

DONE!!
