WebIn A-level maths you are often asked to solve ax2 + bx + c = 0 or some variation of that, where a, b, and c are real numbers (we say that a, b, c ∈ R ). The discriminant, b2 − 4ac, would tell you whether the quadratic equation is soluble. In particular you were told that you needed b2 − 4ac ≥ 0 to solve the quadratic. Why do you need that? WebIn mathematics, a root system is a configuration of vectors in a Euclidean space satisfying certain geometrical properties. The concept is fundamental in the theory of Lie groups …
WebRoot. Where a function equals zero. In this example, −2 and 2 are the roots of the function x2 − 4. But sometimes "root" is used as a quick way of saying "square root", for example "root 2" means √2. See: Square Root.
