Question: Second Solution: Verify that if the discriminant of equation (1) as given by ( = b2 - 4ac is zero, so that b2 = 4ac

Second Solution: Verify that if the discriminant of equation (1) as given by ( = b2 - 4ac is zero, so that b2 = 4ac and the characteristic root is r = - b/2a, then substituting y = v(t)e-(b/2a)r into ( I ) leads to the condition v"(t) = 0?
