Homework Statement
Solve the modular equation x2 + 8x ≡ 0 (mod 56)
Homework Equations
Let a, b = integer
n|(a - b), written as a ≡ b (mod n)
The Attempt at a Solution
I tried to separate them, and got
2|x2 + 8x or x2 + 8x ≡ 0 (mod 2) as well as
7|x2 + 8x or x2 + 8x ≡ 0 (mod 7)
but I'm a bit stuck now, and I'm pretty sure they might be wrong?
How should I be solving this? Thanks!
