यदि (f(x)=x-3) और (g(x)=x-2) हों, तो ((f-g)(x)=0) के वास्तविक हल कौन-से हैं?
If (f(x)=x-3) and (g(x)=x-2), what are the real solutions of ((f-g)(x)=0)?
Explanation opens after your attempt
A. (x=0,1)
Concept
(x-3-x-2=x-2(x-1)=0), so (x=0) or (x=1). Factoring gives solutions quickly.
Why this answer is correct
The correct answer is A. (x=0,1). (x-3-x-2=x-2(x-1)=0), so (x=0) or (x=1). Factoring gives solutions quickly.
Exam Tip
(x-3-x-2=x-2(x-1)=0), इसलिए (x=0) या (x=1)। गुणनखंड करने से हल तेजी से मिलते हैं।
