यदि (p(x)=5x-6), तो (p(x+1)-p(x)) क्या है?
If (p(x)=5x-6), what is (p(x+1)-p(x))?

B. 5
Simple Explanation
दिया है, \(p(x)=5x-6\)। इसलिए \(p(x+1)=5(x+1)-6=5x-1\)। अतः \(p(x+1)-p(x)=(5x-1)-(5x-6)=5\)। इसलिए सही उत्तर 5 है। \(5x\) लेने पर स्थिर पदों का अंतर नहीं निकलेगा। परीक्षा टिप: रैखिक बहुपद \(ax+b\) के लिए \(p(x+1)-p(x)=a\), अर्थात \(x\) का गुणांक होता है। / Given \(p(x)=5x-6\), we get \(p(x+1)=5(x+1)-6=5x-1\). Hence, \(p(x+1)-p(x)=(5x-1)-(5x-6)=5\). Therefore, 5 is the correct answer. Choosing \(5x\) ignores the cancellation of the variable terms and the difference between the constant terms. Exam tip: for a linear polynomial \(ax+b\), \(p(x+1)-p(x)=a\), the coefficient of \(x\).
