2(a^2+b^2) =(a+b) ^2​

Answer»

HERE IS UR ANSWER DEAR,

2( {a}^{2} + {b}^{2} ) = {(a + b)}^{2}

2 {a}^{2} + 2 {b}^{2} = {a}^{2} + 2ab + {b}^{2}

because ,

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

2 {a}^{2} + 2 {b}^{2} - {a}^{2} - {b}^{2} = 2ab

{a}^{2} + {b}^{2} = 2ab

{a}^{2} + {b}^{2} - 2ab = 0

{(a - b)}^{2} = 0
