This widget will solve linear congruences for you. The equation 3x==75 mod 100 (== means congruence), input 3x into Variable and Coeffecient, input 100 into modulus, and input 75 into the last box.
1 lip 2024 · Quadratic Congruence Equation. Download Wolfram Notebook. A congruence of the form. (1) where , , and are integers. A general quadratic congruence can be reduced to the congruence. (2) and can be solved using excludents, although solution of the general polynomial congruence. (3)
Solving the quadratic congruence x 2 ≡ a (mod m) This works for m with up to say 20 digits, due to the limitations of the program used to factor m. Using the Chinese remainder theorem, the problem is reduced to the case of a prime power p n:
That is the task of solving quadratic congruences, the modular equivalent to the well-known quadratic equations. 🔗. 🔗. Recall that a (single-variable) quadratic expression is one of the form , a x 2 + b x + c, and a quadratic equation would be of the form . a x 2 + b x + c = 0.
