-106 * 125 = -13250 -13250 mod 215 = -135 to make it positive we add 215, to make it 80. Note that congruency is about cycles so we can add the mod to get to a positive solution.
I can provide a hint: use the Chinese Remainder Theorem (CRT). It involves solving the congruence modulo the prime factors of 77 (i.e., 7 and 11) and then combining the solutions.
thank you , very clear explanation !
thank you, You saved me for my exam
If we get negative value of x how to make it positive
-106 * 125 = -13250
-13250 mod 215 = -135
to make it positive we add 215, to make it 80. Note that congruency is about cycles so we can add the mod to get to a positive solution.
Thank you
congruence pls
solve for me this question ,23x^2-8x+34=0mod77
