    I think you took the wrong factors for the equation 'h^2 - 12h + 64 = 0' because when you multiply -16*4 you get -64 instead of getting +64

    "Two sides of a parallelogram are formed by parts of the line 2x -y = -9 and x - 2y = -9." I was able to find the find co-ordinates of the vertex where they intersect which is (-3,3). The next part says that another vertex of the parallelogram is the point (2,1) and I have to find the equations...
