If b 2-4ac 0

WebSo, b 2 – 4ac = 0 (since 16 – 16 = 0), and thus the discriminant is zero. This means that the quadratic has one repeated real root. The repeated real root is x = -2. You can see this by factoring x 2 + 4x + 4 as (x + 2) (x + 2). (You can also use the quadratic formula with a = 1, b = 4, and c = 4 to verify this solution.) Look At The Graph Webthen the type of conic section that the above equation represents can be found using the discriminant of the equation, which is given by B^ {2} - 4AC B2 −4AC for (1), (1), or …
