⚫In this question we have to give the expanded form of the following identities:-

⭕(x + a) (x + b) = x² + x(a + b) + ab

⭕(x + a) (x - b) = x² + x(a - b) - ab

⭕(x - a) (x + b) = x² + x(b - a) - ab​

⭕(x - a) (x - b) = x² - x(a + b) + ab​

⭕(a + b)² = a² + 2ab + b²

⭕(a - b)² = a² - 2ab + b²

⭕(a + b) (a - b) = a² - b²

⭕(a + b)³ = a³ + b³ + 3ab (a + b)

⭕(a - b)³ = a³ - b³ - 3ab (a - b)
