Quadratic Congruences the Quadratic Formula and Euler's

Quadratic CongruencesEuler’s CriterionRoot Counting Corollary The number of solutions (modulo n) to the quadratic congruence ax2 + bx + c 0 (mod n) is the product of the numbers of solutions (modulo pm i i) to ax2 + bx + c 0 (mod pm i i); i = 1;2;:::;k: We have therefore reduced the study of quadratic congruences to the case of prime power

How to solve quadratic congruences?

Quadratic Congruences, II Now that we have handled the troublesome cases, we can solve the quadratic equation the usual way by completing the square. Explicitly, with f(x) = ax2+ bx + c, we can write 4af(x) = (2ax + b)2+ (4ac b2).

How to prove congruence in geometry?

19. If the area of two similar triangles are equal, prove that they are congruent. 20. If A (–2, 1), B (a, 0), C (4, b) and D (1, 2) are the vertices of a parallelogram ABCD, find the values of a and b.

How do you find the congruence equation with D = 4?

(b) Note that d = gcd (8, 28) = 4, and d = 4 does divide 12. Thus the equation has d = 4 solutions. Dividing each term in the equation by d = 4 we obtain the congruence equation (11.7) which has a unique solution. 2x ? 3 (mod 7) (11.7)

How do you find the unique solution of a congruence equation?

EXAMPLE 11.18 (a) Consider the congruence equation 3x ? 5 (mod 8). Since 3 and 8 are coprime, the equation has a unique solution. Testing the integers 0, 1, . . ., 7, we ?nd that 3 (7) = 21 ? 5 (mod 8) Thus x = 7 is the unique solution of the equation. (b) Consider the linear congruence equation 33x ? 38 (mod 280)
