Question

$\huge \underline\mathfrak \red{question} \star$
Write the value of. -
(a+b)^2 + (a-b)^2​

Answer 1

$({a + b})^{2} + ( {a - b})^{2} \\ \\ => ({a}^{2} + {b}^{2} + 2ab) +( {a}^{2} + {b}^{2} - 2ab) \\ \\ =>{a}^{2} + {b}^{2} + 2ab + {a}^{2} + {b}^{2} - 2ab \\ \\=> 2( {a}^{2} + {b}^{2} )$

Answer 2

Answer:

$\huge \underline\mathfrak \blue{answer} \star$

(a+b)^2 + (a-b)^2

= a^ 2 + b^2 + 2ab + [ a^ 2 + b^2 + 2ab ]

= 2 ( a^ 2 + b^2 + 2ab )

= 2a^2 + 2b^2
