Question

algebra algebra formula​

Answer 1

• a² – b² = (a-b)(a+b)

• (a+b)² = a² + 2ab + b²

• (a-b)² = a² – 2ab + b²

• a² + b² = (a-b)² +2ab

• (a+b+c)² = a²+b²+c²+2ab+2ac+2bc

• (a-b-c)² = a²+b²+c²-2ab-2ac+2bc

• a³-b³ = (a-b) (a² + ab + b²)

• a³+b³ = (a+b) (a² – ab + b²)

• (a+b)³ = a³+ 3a²b + 3ab² + b³

• (a-b)³ = a³- 3a²b + 3ab² – b³
