What is the simplified form of ( (2a+b)2+(2a-b)2 )?
Explanation opens after your attempt
A. \(8a^2+2b^2\)
Concept

Why this answer is correct
The correct answer is A. \(8a^2+2b^2\). ( (u+v)2+(u-v)2=2u-2+2v-2 ). With (u=2a) and (v=b), the result is \(8a^2+2b^2\).
Exam Tip
( (u+v)2+(u-v)2=2u-2+2v-2 ) है। यहाँ (u=2a) और (v=b) रखने पर \(8a^2+2b^2\) मिलता है।
