Question

write 10 algebraic identities

Answer 1

here is you answer.......

Answer 2

Algebraic identities:

★ (a + b)² = a² + b² + 2ab

★ (a - b)² = a² + b² - 2ab

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

★ (a² - b²) = (a + b)(a - b)

★ (a + b)³ = a³ + b³ + 3ab(a + b)

★ (a - b)³ = a³ - b³ - 3ab(a - b)

★ a³ + b³ = (a + b)(a² + b² - ab)

★ a³ - b³ = (a - b)(a² + b² + ab)

★ a³ + b³ + c³ - 3abc = (a + b + c)(a² + b² + c² - ab - bc - ac)

★ if (a + b + c) = 0 then, a³ + b³ + c³ = 3abc
