Are you sure you have this entered correctly?

I would factor this.. common factor is 2^x. So you would have 2^x(x^2 - 1) = 0 Then you have the difference of two squares so you have 2^x(x + 1)(x - 1) = 0 So every where there is an "x" there is an answer. So x + 1 would give you an answer of -1 ... x - 1 would give you an answer of 1 When does 2^x = 0?

x would be 0, so -1 and 1 would work
