Question

(a-b) whole square + (a+b) whole square

Answer 1

Answer:

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

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

Step-by-step explanation:(a-b)+(a+b)

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

=2a^2+2b^2

Answer 2

Answer:

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

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

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

= 2a^2 + 2b^2

= 2(a^2 + b^2)
