Last updated: June 2026 | By Patchworkr Team
Reverse FOIL is a factoring method for quadratic trinomials. It works by finding two numbers that multiply to ac and add to b, then splitting the middle term and factoring by grouping.
x^2 - 5x + 6 factors to (x - 2)(x - 3).
The calculator returns a message instead of forcing a false factorization.
No. This version is designed for integer coefficients only.
Because the middle term can often be split in more than one order before factoring.
No. The calculator supports general quadratic trinomials.
