यदि (p(x)=2x-2-7x+3), तो (p(x+1)-p(x-1)) क्या होगा?
If (p(x)=2x-2-7x+3), what will (p(x+1)-p(x-1)) be?
Explanation opens after your attempt
A. (8x-14)
Concept
(p(x+1)=2x-2-3x-2) and (p(x-1)=2x-2-11x+12), so the difference is (8x-14). Substitute the whole expression in place of (x).
Why this answer is correct
The correct answer is A. (8x-14). (p(x+1)=2x-2-3x-2) and (p(x-1)=2x-2-11x+12), so the difference is (8x-14). Substitute the whole expression in place of (x).
Exam Tip
(p(x+1)=2x-2-3x-2) और (p(x-1)=2x-2-11x+12), इसलिए अंतर (8x-14) है। पूरे व्यंजक को (x) की जगह रखें।
