Four Terms?

Use Factoring by Grouping.

Essential Factoring Formulas

Core algebraic identities implemented in our calculator engine:

Difference of Squares

a² − b² = (a − b)(a + b)

Difference of Cubes

a³ − b³ = (a − b)(a² + ab + b²)

Sum of Cubes

a³ + b³ = (a + b)(a² − ab + b²)

Perfect Square Trinomial (+)

a² + 2ab + b² = (a + b)²

Perfect Square Trinomial (−)

a² − 2ab + b² = (a − b)²

Greatest Common Factor (GCF)

ab + ac = a(b + c)
