Quadratic roots solver

Client

Solve quadratic equations in one variable.

Quadratic roots

Solves ax²+bx+c=0 from three comma coefficients—reports real or complex roots in a+bi form when discriminant is negative. Processing runs in your browser—Toolcore does not need your paste for the core operation on this page.

Educational statistics only—confirm assumptions before production analysis.

How to use

Paste or type in the main field, then read the output below. Use Load example when available, or open the page with ?q= / ?qb= so tickets and agents share the same input.
