यदि (p(x)=2x-2-5x+3), तो (p(x+2)-p(x)) क्या होगा?
If (p(x)=2x-2-5x+3), what will (p(x+2)-p(x)) be?
Explanation opens after your attempt
B. (8x+2)
Concept
(p(x+2)=2(x+2)2-5(x+2)+3=2x-2+3x+1), so the difference is (8x+2). Substitute the whole (x+2) correctly.
Why this answer is correct
The correct answer is B. (8x+2). (p(x+2)=2(x+2)2-5(x+2)+3=2x-2+3x+1), so the difference is (8x+2). Substitute the whole (x+2) correctly.
Exam Tip
(p(x+2)=2(x+2)2-5(x+2)+3=2x-2+3x+1), इसलिए अंतर (8x+2) है। पूरे (x+2) को सही जगह रखें।
