Question

(a+b) ²=???????????????​

Answer 1

$\huge\fcolorbox{red}{gold}{αηѕωєя}$

(a + b)²=(a + b) * (a + b)

Therefore,

(a + b)² =a*a+ab+ba+b*b

(a + b)² = a² + 2ab+ b²

_____________________________

This is an algebraic identity.

(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

Some other identities are:

(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

And

(a+b)*(a-b) = a² - ab + ba + b²

(a+b)*(a-b) = a² - b²

Answer 2

Answer:

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