The graph of the equation y = ax^2 + bx + c, where a, b, and c are constants, is a parabola with axis of symmetry x = -10. Find b/a.
+191 The graph of the equation y = ax^2 + bx + c, where a, b, and c are constants, is a parabola with axis of symmetry x = -10. Find b/a.
According to The Vieta's Formula, we can know
that -b/2a = -10, and b = 20a, and b/a = 20
