Answer 1

Answer:

a²-b² = (a+b)(a-b)

a²-b² = (a+b)(a-b)(a+b)(a-b) = a²-b²

a²-b² = (a+b)(a-b)(a+b)(a-b) = a²-b²(a+b)(a+b) = (a+b)² = a²+b²+2ab

a²-b² = (a+b)(a-b)(a+b)(a-b) = a²-b²(a+b)(a+b) = (a+b)² = a²+b²+2ab(a+b)(b-a) = b²-a²

a²-b² = (a+b)(a-b)(a+b)(a-b) = a²-b²(a+b)(a+b) = (a+b)² = a²+b²+2ab(a+b)(b-a) = b²-a²(a-b) (a-b) = (a-b)² = a²+b²-2ab.
