Question

(a+b)^2+(a-b)^2 simplify the following​

Answer 1

Answer:

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

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

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

Answer 2

Step-by-step explanation:

${(a + b)}^{2} + {(a - b)}^{2}$

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

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

$2 {a}^{2} + 2 {b}^{2}$

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