Question

(a+b)^2 + (a-b) ^2
pls tell correct answer ​

Answer 1

Answer:

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

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

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

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

Answer 2

Answer:

2(a²+b²)

Step-by-step explanation:

(a+b)²+(a-b)²

=a²+2ab+b²+a²-2ab+b²

=a²+a²+b²+b²+2ab-2ab

=2a²+2b²

=2(a²+b²)
