Question

2(a^2+b^2) =(a+b) ^2. A) a+b=0. B) a=b. C) 2a=b. D) ab=0

​

Answer 1

Answer:

Step-by-step explanation:

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

2 a^2 + 2 b^2 = {a^2 + b^2 + 2ab} ---> Expanding using formula

on Simplifying, we get

a^2 + b^2 = 2ab ,

=> a^2 + b^2 - 2ab = 0;

(a-b)^2 = 0;

where a must be equal to b .

So Go with option B.
