यदि (f(x)=x-2+px+4) और (g(x)=x-2-px+4) हैं, तो ((f-g)(2)=12) होने पर (p) क्या होगा?
If (f(x)=x-2+px+4) and (g(x)=x-2-px+4), what is (p) if ((f-g)(2)=12)?
Explanation opens after your attempt
B. (3)
Concept
(f-g=2px), so ((f-g)(2)=4p=12). This gives (p=3).
Why this answer is correct
The correct answer is B. (3). (f-g=2px), so ((f-g)(2)=4p=12). This gives (p=3).
Exam Tip
(f-g=2px), इसलिए ((f-g)(2)=4p=12)। इससे (p=3) मिलता है।
