please tell someone please explain to me and I will mark you as a brainlist promise ​

Answer 1

Answer:

option d is correct answer

Step-by-step explanation:

using formula a²-b²=(a+b)(a-b)

(a+b)²-(a-b)²=(a+b-a+b)(a+b+a-b)

(a+b)²-(a-b)²=(2b)(2a)=4ab

Answer 2

Answer:

>Here we Have (a+b) ² -(a-b) ²

->we have equation for(a+b)² = a² + 2ab + b²

->we have equation for(a-b)² = a² - 2ab + b²

->so we can use it and we write below step

->(a² + 2ab + b² )-( a² - 2ab + b² )

->after open the braces we got,

->a² + 2ab + b² - a² +2ab - b²

->2ab+2ab =4ab

->so based on above simplification answer is 4ab
