Question

if x=3 - 2√3 then the value of (x+1/x) can be written in the form of a+ b√3 what is the value of b​

Answer 1

answer:

a=2

b= -8/3

Step-by-step explanation:

x=3-2root3

so 1/x = 1 / (3-2root3)

rationalization, multiply numerator and denominator by 3+2root3(so that we get a²-b² form)

1/x= 3 + 2root3/-3

so x+1/x = 2 - 8root3/3

a=2

b= -8/3
