यदि (f(x)=2x+1) और (g(x)=x-4) हों, तो ((f+g)(x)=0) के लिए (x) का मान क्या है?
If (f(x)=2x+1) and (g(x)=x-4), what is the value of (x) for ((f+g)(x)=0)?
Explanation opens after your attempt
A. (1)
Concept
((f+g)(x)=3x-3), so (3x-3=0) gives (x=1). First form the sum, then solve the equation.
Why this answer is correct
The correct answer is A. (1). ((f+g)(x)=3x-3), so (3x-3=0) gives (x=1). First form the sum, then solve the equation.
Exam Tip
((f+g)(x)=3x-3), इसलिए (3x-3=0) से (x=1)। पहले sum बनाएं, फिर equation solve करें।
