यदि (f(x)=x-3) और (g(x)=x-2) हैं, तो ((f-g)(x)) के शून्य कौन से हैं?
If (f(x)=x-3) and (g(x)=x-2), what are the zeroes of ((f-g)(x))?
Explanation opens after your attempt
Correct Answer
A. (0,1)
Concept
((f-g)(x)=x-3-x-2=x-2(x-1)), so the zeroes are (x=0) and (x=1). Factorisation is the fastest method at expert level.
Why this answer is correct
The correct answer is A. (0,1). ((f-g)(x)=x-3-x-2=x-2(x-1)), so the zeroes are (x=0) and (x=1). Factorisation is the fastest method at expert level.
Exam Tip
((f-g)(x)=x-3-x-2=x-2(x-1)), इसलिए शून्य (x=0) और (x=1) हैं। गुणनखंडन विशेषज्ञ स्तर पर सबसे तेज तरीका है।
