\(y^2-10y+25\) का गुणनखंडन कौन सा है?
Which is the factorisation of \(y^2-10y+25\)?
Explanation opens after your attempt
C. ((y-5)2)
Concept
\(25=5^2\) and \(-10y=-2\cdot5y\). So (y-2-10y+25=(y-5)2).
Why this answer is correct
The correct answer is C. ((y-5)2). \(25=5^2\) and \(-10y=-2\cdot5y\). So (y-2-10y+25=(y-5)2).
Exam Tip
\(25=5^2\) और \(-10y=-2\cdot5y\) है। इसलिए (y-2-10y+25=(y-5)2) है।
