यदि (p(x)=3x-2-2x+5), तो (p(2x)) क्या है?
If (p(x)=3x-2-2x+5), what is (p(2x))?
Explanation opens after your attempt
A. \(12x^2-4x+5\)
Concept
(p(2x)=3(2x)2-2(2x)+5=12x-2-4x+5). Square the whole (2x).
Why this answer is correct
The correct answer is A. \(12x^2-4x+5\). (p(2x)=3(2x)2-2(2x)+5=12x-2-4x+5). Square the whole (2x).
Exam Tip
(p(2x)=3(2x)2-2(2x)+5=12x-2-4x+5)। पूरे (2x) का वर्ग करें।
