Factoring Calculator
Two tools in one: factor ax² + bx + c with the full factor-pair hunt shown step by step, or expand a product of binomials to FOIL-check your work.
Factor ax² + bx + c
Integer coefficients only. If it does not factor over the integers, the tool will tell you honestly.
Expand (ax + b)(cx + d)
The FOIL check: expand a product of binomials to verify a factorization.
