यदि (f(x)=x-2+2) और (g(x)=4x) हों, तो ((f+g)(x)) को complete square form में कैसे लिखा जा सकता है?
If (f(x)=x-2+2) and (g(x)=4x), how can ((f+g)(x)) be written in complete square form?
Explanation opens after your attempt
A. ((x+2)2-2)
Concept
((f+g)(x)=x-2+4x+2=(x+2)2-2). In completing the square, add and subtract the square of half the coefficient.
Why this answer is correct
The correct answer is A. ((x+2)2-2). ((f+g)(x)=x-2+4x+2=(x+2)2-2). In completing the square, add and subtract the square of half the coefficient.
Exam Tip
((f+g)(x)=x-2+4x+2=(x+2)2-2)। complete square में आधे coefficient का square जोड़कर घटाते हैं।
