What is the solution to the equation 1/x-1 = x-2/2x^2-2

x=1 and x=-4
neither x=1 or x=-4
x=1
x=-4

x = 1 and x = -4

Step-by-step explanation:

Working is shown in the picture attached.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
