Answer 2

✔ a²-b²= (a+b)(a-b)

✔ (a+b)²= a²+b²+2ab

✔ (a-b)²= a²+b²-2ab

✔ a²+b²= (a-b)²+2ab

✔ (a+b)³= a³+b³+3ab(a+b)

✔ (a-b)³= a³-b³-3ab(a-b)

✔ a³-b³= (a-b)(a²+ab+b²)

✔ a³+b³= (a+b)(a²-ab+b²)

✔ (a+b+c)²= a²+b²+c²+2ab+2bc+2ac

✔ a³+b³+c³-3abc= (a+b+c)(a²+b²+c²-ab-bc-ac)

Hope this helps you......
