\(16x^4-1\) का पूर्ण गुणनखंडन कौन सा है?
Which is the complete factorisation of \(16x^4-1\)?
Explanation opens after your attempt
B. ((2x-1)(2x+1)\(4x^2+1\))
Concept
(16x-4-1=\(4x^2-1\)\(4x^2+1\)). Then (4x-2-1=(2x-1)(2x+1)) also factors.
Why this answer is correct
The correct answer is B. ((2x-1)(2x+1)\(4x^2+1\)). (16x-4-1=\(4x^2-1\)\(4x^2+1\)). Then (4x-2-1=(2x-1)(2x+1)) also factors.
Exam Tip
(16x-4-1=\(4x^2-1\)\(4x^2+1\)) है। फिर (4x-2-1=(2x-1)(2x+1)) भी टूटता है।
