Question

(a+b)²
Identity...................​

Answer 1

Answer:

• (a-b)² = a²+b²-2ab

• (a + b)² = a² + b² + 2ab

• (a - b)² = a² + b² - 2ab

• a² - b² = (a + b)(a - b)

• a³ - b³ = (a - b)(a² + ab + b²)

• a³ + b³ = (a + b)(a² - ab + b²)

• (a - b)³ = a³ + b³ + 3ab(a + b)

• (a + b)³ = a³ - b³ - 3ab(a - b)

• a² - b² = (a + b)(a - b)

• (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ac

hope this answer helps uh!!!

Answer 2

(a+b)^2 = a^2 + b^2 + 2ab
