यदि (f(x)=x-2-1) और (g(x)=x-1) हों, तो ((f-g)(x)) का factorized form क्या होगा?
If (f(x)=x-2-1) and (g(x)=x-1), what is the factorized form of ((f-g)(x))?
Explanation opens after your attempt
A. (x(x-1))
Concept
((f-g)(x)=x-2-1-(x-1)=x-2-x=x(x-1)). Keep the signs correct in subtraction.
Why this answer is correct
The correct answer is A. (x(x-1)). ((f-g)(x)=x-2-1-(x-1)=x-2-x=x(x-1)). Keep the signs correct in subtraction.
Exam Tip
((f-g)(x)=x-2-1-(x-1)=x-2-x=x(x-1))। subtraction में signs सही रखें।
