Quick Answer
Factoring Calculator: GCF · cross method · perfect square. Factoring Calculator uses standard math formulas to compute accurate results instantly.
Factorization
2x² + 7x + 3 = (x+3)(2x+1)
Factoring steps
- 1Cross-multiplication: need m·n = a·c = 6 with m+n = b = 7
- 2Split: 2x² + 7x + 3 = (1x+3)(2x+1)
- 3Result: (x+3)(2x+1)
Common factorizations
| x²+5x+6 | (x+2)(x+3) |
| x²−5x+6 | (x−2)(x−3) |
| x²−9 | (x+3)(x−3) |
| x²+6x+9 | (x+3)² |
| 2x²+7x+3 | (2x+1)(x+3) |
| x²−1 | (x+1)(x−1) |
| 6x²−x−2 | (3x−2)(2x+1) |
Special product formulas
| a²−b² | (a+b)(a−b) | Difference of squares |
| a²±2ab+b² | (a±b)² | Perfect square |
| a³+b³ | (a+b)(a²−ab+b²) | Sum of cubes |
| a³−b³ | (a−b)(a²+ab+b²) | Difference of cubes |
Strategy order: ① extract the GCF first; ② check special formulas (difference of squares, perfect square); ③ cross-multiplication for ax²+bx+c — find m·n = a·c and m+n = b; ④ if the discriminant is a perfect square but no integer split appears, factor using roots. A quadratic is irreducible over the reals iff b²−4ac < 0.
