| 释义 | quadratic equation noun[ C ] uk /kwɒdˌræt.ɪk ɪˈkweɪ.ʒən/ us /kwɑːdˌræt̬.ɪk ɪˈkweɪ.ʒən/ an equation that includes an unknown value that is multiplied by itself only once, and does not include an unknown value multiplied by itself more than once: 二次方程式 In the quadratic equation, 2y2+3y=14, y=2 or y=-3½.在二次方程式2y2+3y=14中，y=2或y=-3½。 Calculations & calculating algebraic algebraically algo algorithmic amount calculate integration interpolation inverse function linear equation mathematical matrix miscalculate miscount operator sum sum total tot something up triangulate work something out quadratic equation | American Dictionaryquadratic equation noun[ C ] us/kwɑˈdræt̬·ɪk ɪˈkweɪ·ʒən/ algebra an equation (= mathematical statement) that includes an unknown value multiplied by itself only once, and does not include an unknown value multiplied by itself more than once; an equation that can be expressed as ax²+bx+c=0, when a does not equal zero Examples of quadratic equationquadratic equation The joint motion is curve fitted into a quadraticequation by using three data points: the current value and two previous values. By solving the quadraticequation of the models, the turning points of the deforestation/income relationship can be found. But even the solution of a quadraticequation is not necessary. There are three basic shapes of a quadraticequation: linear, concave, and convex. Using the quadraticequation, a prediction is made as to how much time would elapse before a limit is reached. Then (6.20) becomes a quadraticequation for (r). The quadraticequation, however, can be efficiently solved on a computer. Alternatively, example (34) is best understood in the context of the solution of the quadraticequation below. However, where the cubic term is not statistically significant (at 90 per cent confidence level) a quadraticequation is estimated. This can be substituted into the quadraticequation defining the group. The quadraticequation can teach us to be humble. From the Hansard archive Example from the Hansard archive.

From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 He cited the quadraticequation as an example of the sort of irrelevant topic that pupils study. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 One finishes up with a quadraticequation to which there is no solution.
