Solution For Find the separate equations of the lines represented by the equation x^2 - 4y^2 - 2x + 4y + 0.Ans: x -2y -2 = 0, x -2y = 0. In this case, we multiply the first equation by 4 to give 12x+4y=28.Then minus the 2nd equation from this to give 10x+0y=20.Now divide by 10 to get x=2. (xA+yB)·C = (x+5y, x+2y,−x−4y)·(2,2,3) = 2x+ 10y +2x+4y −3x−12y = x+2y. Therefore (xA + yB) · C = 0 if and only if x = −2y. This means that the vectors xA + ...
