चार भागों \(y^2\), \(4y\), \(4y\) और \(16\) से बना वर्ग किस अभिव्यक्ति को दिखाता है?
A square made of four parts \(y^2\), \(4y\), \(4y\), and \(16\) shows which expression?
Explanation opens after your attempt
C. \((y+4)^2\)
Concept
The sum of the parts is \(y^2+8y+16\). It equals \((y+4)^2\).
Why this answer is correct
The correct answer is C. \((y+4)^2\). The sum of the parts is \(y^2+8y+16\). It equals \((y+4)^2\).
Exam Tip
भागों का योग \(y^2+8y+16\) है। यह \((y+4)^2\) के बराबर है।
