Question

1 . a²+b² =
2. a²× b² =
please give both formulas

Answer 1

1. a square + b square is equal to a + b whole square minus 2 a b
2. a square multiplied with b square gives a b whole square

Answer 2

Here is your answer......

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

1. a²+b² = (a+b)² - 2ab

2.  a²× b² = [(a+b)² - (a²+b²)]²

I hope it helps you ^_^
