Question

if x=1/2-√3 find the value of x²-1/x²
pls........ answer this question correctly
it's really very urgent ​

Answer 1

Answer:

hope it helps , if it does kindly make me as brainliest.

Step-by-step explanation:

x= 1/2 - √3

on squaring both sides we get

x^2 = (1/2 - √3)^2

x^2 =  13/4 - √3

now 1 / x^2 = by rationalising x^2

we get, 52 + 16√3 / 121

now x^2 - 1/x^2 = 13/4 -√3 - 52 - 16√3/ 121

= -195 /4 - 17√3
