Question

simplify the following​

Answer 1

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

(a2+2ab+b2)+(a2-2ab+b2)

a2+2ab+b2+a2-2ab+b2

2a2+2b2

Answer 2

Answer:

$( {a + b})^{2} + ({ \alpha - b})^{2} \\ {(a + b)}^{2} - {( - a + b)}^{2} \\ (a +b) + ( - a + b) \times (a + b) - ( - a + b) \\ 2b \times 2a \\ 4ab$

OR

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