\(4x^2-4x+1=0\) की दोनों जड़ों का मान क्या है?
What is the value of both roots of \(4x^2-4x+1=0\)?
Explanation opens after your attempt
A. \(\frac{1}{2}\)
Concept
(4x-2-4x+1=(2x-1)2). Therefore the equal root is \(x=\frac{1}{2}\).
Why this answer is correct
The correct answer is A. \(\frac{1}{2}\). (4x-2-4x+1=(2x-1)2). Therefore the equal root is \(x=\frac{1}{2}\).
Exam Tip
(4x-2-4x+1=(2x-1)2) है। इसलिए समान जड़ \(x=\frac{1}{2}\) है।
