Question

(a+b)^2= (a-b)^2+______​

Answer 1

Answer:

+4ab

Step-by-step explanation:

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

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

so (a+b)^2=(a-b)+4ab

Answer 2

Answer:4ab

Step-by-step explanation:

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

a^2+ b^2+ 4ab = a^2+ b^2

(a+b) (a-b) + 4ab = (a+b) (a-b)

[{ (a+b) (a-b) = a^2- b^2 = (a-b)^2}]

(a+b)^2+ 4ab = (a+b)^2
