Question

(a-b)2+(a+b)2 =pls solve? ​

Answer 1

$\huge{\mathfrak{\blue{\underline{Answer}}}}$

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

Answer 2

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

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

= a^2 + b^2 + a^2 + b^2

= 2a^2 + 2b^2

= 2(a^2 + b^2)
