Plugging these values into the solving formula written at the beginning, you have x_{1,2} = \frac{-1 \pm \sqrt{1^2-4*1*1}}{2*1} = -1/2 \pm \sqrt{-3}/2 Since the discriminant is -3, there are no real solutions. Section 5.1 Generating Functions. There is an extremely powerful tool in discrete mathematics used to manipulate sequences called the generating function. The idea is this: instead of an infinite sequence (for example: \(2, 3, 5, 8, 12, \ldots\)) we look at a single function which encodes the sequence.Quadratic equations x2 x 1 = 0 We think you wrote: This solution deals with quadratic equations.
