Question

(a+b) ^2=a^2-2ab+b^2​

Answer 1

Ответ:

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

Answer 2

I'm sorry, but that equation is incorrect. The correct expansion of $(a + b)^2$ is:

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

This is known as the distributive property of multiplication over addition. If you were looking for something else, please let me know!
