... 2x2 + 3x + 1 = 8 is a quadratic equation. 3x + 2 = 6 and x3 + 2x – 4 = x are not quadratic equations. A solution of a quadratic equation is a value of the variable that makes the equation hold. E.g. 5 is a solution of the equation x 2 − 2 x − 15 = 0, since 52-2×5-15=0. -3 is also a solution of the e ...

Non-congruent numbers, odd graphs and the Birch–Swinnerton
... 2t−1 k hK ⇔ the directed graph RG(D) is odd. (For the definition of the graph F G(D) and the odd graph, see [2]. Notice that our notation F G(D) is just the notation G(−D) in [2]. The definition of the Rédei graph RG(D) is given in Definition 0.3 below.) In the following, we will give the proof of ...
