Determine whether the conjecture is true or false. if false, give a counterexample. given: x2+4=8 conjecture: x=−2

We start with the given equation

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

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
