Which is one complete factorised form of \(a^6-b^6\)?

Explanation opens after your attempt
Correct Answer

B. ( (a-b)(a+b)\(a^2+ab+b^2\)\(a^2-ab+b^2\) )

Step 1

Concept

\(a^6-b^6\) can be fully factored using both cube and square identities. Exam tip: factor both \(a^3-b^3\) and \(a^3+b^3\) further.

Step 2

Why this answer is correct

The correct answer is B. ( (a-b)(a+b)\(a^2+ab+b^2\)\(a^2-ab+b^2\) ). \(a^6-b^6\) can be fully factored using both cube and square identities. Exam tip: factor both \(a^3-b^3\) and \(a^3+b^3\) further.

Step 3

Exam Tip

\(a^6-b^6\) को घन और वर्ग दोनों पहचान से पूर्ण रूप में तोड़ा जा सकता है। परीक्षा में \(a^3-b^3\) और \(a^3+b^3\) दोनों को आगे तोड़ें।
