If the quadratic equation MX & sup2; - 2x-1 = 0 with respect to X has no real root, then the image of the linear function y = (M + 1) x-m does not pass through which image

If the quadratic equation MX & sup2; - 2x-1 = 0 with respect to X has no real root, then the image of the linear function y = (M + 1) x-m does not pass through which image

Since the quadratic equation MX & sup2; - 2x-1 = 0 has no real root, it has
∆=4+4m
