We start with the given equation

x^{2} + 4 = 8

Now, we solve the equation, we subtract 4 on either side,

x^{2} +4 -4 = 8-4

x^{2}  = 4

x = \sqrt{4}

\sqrt{4 }  = +2 and -2

x = +2 or -2

So, x= +2 and x =-2

Since the given conjuncture says X=-2, we can conclude that the given conjuncture is TRUE
