Question

the identity (a+b)² =________​

Answer 1

Answer:

$(a + b) {}^{2} = {a}^{2} + {b}^{2} + 2ab$

Answer 2

REQUIRED ANSWER : -

$\longrightarrow$(a+b)² = (a+b)*(a+b)

$\longrightarrow$(a+b)*(a+b) = a² + ab + ba + b²

$\longrightarrow$(a+b)*(a+b) = a² + b² + 2ab

$\longrightarrow$(a+b)² = a² + b² + 2ab

✿ ADDITIONAL INFORMATION

➠ (a-b)² = (a-b)*(a-b)

➠ (a-b)*(a-b) = a² - ab - ba + b²

➠ (a-b)*(a-b) = a² + b² - 2ab

➠ (a-b)² = a² + b² - 2ab
