(ab)²

Step-by-step explanation:

hope it's will help u

Answer 2

Answer:

(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

Good Luck !!!
