  • You use the quadratic formula! No, really. But you need to interpret the terms correctly: rather than "dividing" by $2a$ (here, $2$) you need to multiply by a number $r$ such that $2.$ The general idea can be used even when we are solving a quadratic congruence modulo $m$, where $m$ is not prime.
