(Definition) A modular congruence is a kind of equation (or a system of congruence, with at least one unknown variable) valid according to a linear congruence (modulo/modulus). With modulo, rather than talking about equality, it is customary to speak of congruence.

1 lip 2024 · An equation of the form f (x)=b (mod m), (1) where the values of 0<=x<m for which the equation holds are sought. Such an equation may have none, one, or many solutions. There is a general method for solving both the general linear congruence equation ax=b (mod m) (2) and the general quadratic congruence equation a_2x^2+a_1x+a_0=0 (mod n).
To solve a polynomial equation write it in standard form (variables and canstants on one side and zero on the other side of the equation). Factor it and set each factor to zero. Solve each factor.
