Prove the identity (a+b)^2=a^2+b^2+2ab

1.	Prove the identity (a+b)^2=a^2+b^2+2ab
Answer» Answer: Step-by-step explanation: (a + b ) ^ 2 is the same as (a+b)(a +b) so we EXPAND the brackets, a(a+b) + b(a+b) a^2 + AB + ab + b^2 collect liked terms it then equals to a^2 + b^2 + 2AB

Answer»

Answer:

Step-by-step explanation:

(a + b ) ^ 2 is the same as (a+b)(a +b)

so we EXPAND the brackets,

a(a+b) + b(a+b)

a^2 + AB + ab + b^2

collect liked terms it then equals to

a^2 + b^2 + 2AB
