यदि दृश्य मॉडल में \(y^2\) वर्ग से दो \(4y\) आयत घटाए जाते हैं और \(16\) वर्ग जोड़ा जाता है, तो पहचान क्या है?

If a visual model subtracts two \(4y\) rectangles from a \(y^2\) square and adds a \(16\) square, what is the identity?

Explanation opens after your attempt
Correct Answer

A. \((y-4)^2=y^2-8y+16\)

Step 1

Concept

Subtracting two \(4y\) parts gives the middle term \(-8y\). Exam tip: remember \(4^2=16\).

Step 2

Why this answer is correct

The correct answer is A. \((y-4)^2=y^2-8y+16\). Subtracting two \(4y\) parts gives the middle term \(-8y\). Exam tip: remember \(4^2=16\).

Step 3

Exam Tip

दो \(4y\) घटने से बीच का पद \(-8y\) बनता है। परीक्षा में \(4^2=16\) याद रखें।
