Question

Say 10 words I will give 20 points​

Answer 1

Answer:

'10 words' -- I said it. Now give my points..

Just kidding. By the way. Why are you giving points?

So in return I will share some algebraic formulae:

(a+b)² = a²+2ab+b²

(a-b)² = a²-2ab+b²

a²+b² = (a+b)²-2ab

a²+b² = (a-b)²+2ab

a²-b² = (a+b)(a-b)

2(a²+b²) = (a+b)²+(a-b)²

4ab = (a+b)²-(a-b)²

(a+b)³ = a³+3a²b+3ab²+b³

(a+b)³ = a³+b³+3ab(a+b)

(a-b)³ = a³-3a²b+3ab²-b³

10 formulae instead of 10 words.

Hope it will help. Thank you!
