एक छात्र ने ((x-4)2) का मॉडल \(x^2-16\) लिख दिया। कौन-सा भाग छूट गया?
A student wrote the model of ((x-4)2) as \(x^2-16\). Which part was missed?
Explanation opens after your attempt
D. (-8x+32)correction difference
Concept
The correct expansion is \(x^2-8x+16\), so the difference from \(x^2-16\) is (-8x+32). In exams keep square of difference and difference of squares separate.
Why this answer is correct
The correct answer is D. (-8x+32) / correction difference. The correct expansion is \(x^2-8x+16\), so the difference from \(x^2-16\) is (-8x+32). In exams keep square of difference and difference of squares separate.
Exam Tip
सही विस्तार \(x^2-8x+16\) है, इसलिए \(x^2-16\) से अंतर (-8x+32) है। परीक्षा में अंतर का वर्ग और वर्गों का अंतर अलग रखें।
