यदि (f(x)=x-2+x) और (g(x)=x-2-x) हों, तो ((f+g)(x)) क्या होगा?
If (f(x)=x-2+x) and (g(x)=x-2-x), what is ((f+g)(x))?
Explanation opens after your attempt
A. \(2x^2\)
Concept
(x) and (-x) cancel, so ((f+g)(x)=2x-2). Identify opposite terms.
Why this answer is correct
The correct answer is A. \(2x^2\). (x) and (-x) cancel, so ((f+g)(x)=2x-2). Identify opposite terms.
Exam Tip
(x) और (-x) कट जाते हैं, इसलिए ((f+g)(x)=2x-2)। विपरीत पद पहचानें।
