    both real and rational unless imaginary numbers were put into equation (Im assuming not so considering it wasnt mentioned in the question itself), and also one has negative coefficient, theres no need to even consider it. No need to solve

    \[64x^2-16x+1=(8x-1)(8x-1)=0\]

    \[8x-1=0 or 8x-1=0\]

    I'm so confused so it's not two real rational like what Reealcheyenne said?

    There is one root which occurs twice. That is what we call a double root. It corresponds to a point of tangency of the graph to the x axis at that number.
