यदि (f(x)=x-2) और (g(x)=\frac{1}{x}) हों, तो ((f+g)(x)=2) के लिए कौन-सा समीकरण मिलेगा?
If (f(x)=x-2) and (g(x)=\frac{1}{x}), which equation is obtained from ((f+g)(x)=2)?
Explanation opens after your attempt
Correct Answer
A. \(x^3-2x+1=0,\ x\ne 0\)
Concept
Multiplying \(x^2+\frac{1}{x}=2\) by (x) gives \(x^3+1=2x\). The condition \(x\ne 0\) is necessary.
Why this answer is correct
The correct answer is A. \(x^3-2x+1=0,\ x\ne 0\). Multiplying \(x^2+\frac{1}{x}=2\) by (x) gives \(x^3+1=2x\). The condition \(x\ne 0\) is necessary.
Exam Tip
\(x^2+\frac{1}{x}=2\) को (x) से गुणा करने पर \(x^3+1=2x\) मिलता है। \(x\ne 0\) शर्त जरूरी है।
