Answer:
- a² – b² = (a – b)(a + b)
- (a+b)² = a² + 2ab + b²
- a² + b² = (a + b)² – 2ab
- (a – b)² = a² – 2ab + b²
- (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
- (a – b – c)² = a² + b² + c² – 2ab + 2bc – 2ca
- (a + b)³ = a³ + 3a²b + 3ab² + b³
- (a + b)³ = a³ + b³ + 3ab(a + b)
- (a – b)³ = a³ – 3a²b + 3ab² – b³
- a³ – b³ = (a – b)(a² + ab + b²)
- a³ + b³ = (a + b)(a² – ab + b²)
- (a + b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b⁴
- (a – b)⁴ = a⁴ – 4a³b + 6a²b² – 4ab³ + b⁴
- a⁴ – b⁴ = (a – b)(a + b)(a² + b²)
- a⁵ – b⁵ = (a – b)(a⁴ + a³b + a²b² + ab³ + b⁴)
