यदि (f(x)=x-2) और (g(x)=3x) हों, तो वह (x) कौन-सा है जिसके लिए ((f-g)(x)=0)?
If (f(x)=x-2) and (g(x)=3x), which (x) satisfies ((f-g)(x)=0)?
Explanation opens after your attempt
A. (x=0) या (x=3)(x=0) or (x=3)
Concept
((f-g)(x)=x-2-3x=x(x-3)), so (x=0) or (x=3). Remember the zero product rule.
Why this answer is correct
The correct answer is A. (x=0) या (x=3) / (x=0) or (x=3). ((f-g)(x)=x-2-3x=x(x-3)), so (x=0) or (x=3). Remember the zero product rule.
Exam Tip
((f-g)(x)=x-2-3x=x(x-3)), इसलिए (x=0) या (x=3)। शून्य गुणनफल नियम याद रखें।
