Question

ã²+b²= ?
Please tell me as fast as you can ​

Answer 1

$\bf{\boxed{\underline{\mathscr{\red{:→ a^2+b^2=(a-b)^2 + 2ab}}}}}$

(¡) a²+b² = (a+b)² - 2ab

→ a²+2ab+b²-2ab

→ a²+b²

• LHS = RHS

Therefore,

• hence proved!

(ii). a²+b² = (a-b)² + 2ab

→ a²-2ab+b²+2ab

• LHS = RHS

Therefore,

• hence proved!

Hence,

→ a²+b² = (a+b)² - 2ab

'OR'

→ a²+b² = (a-b)² + 2ab

Answer 2

Answer:

ã²+b²= (a-b)^2+2ab
