यदि (f(x)=x-2+2x) और (g(x)=3x-5) हों, तो ((2f-3g)(x)) क्या होगा?
If (f(x)=x-2+2x) and (g(x)=3x-5), what is ((2f-3g)(x))?
Explanation opens after your attempt
A. \(2x^2-5x+15\)
Concept
\(2f=2x^2+4x\) and (3g=9x-15), so the difference is \(2x^2-5x+15\). Watch signs carefully.
Why this answer is correct
The correct answer is A. \(2x^2-5x+15\). \(2f=2x^2+4x\) and (3g=9x-15), so the difference is \(2x^2-5x+15\). Watch signs carefully.
Exam Tip
\(2f=2x^2+4x\) और (3g=9x-15), इसलिए अंतर \(2x^2-5x+15\) है। संकेतों पर विशेष ध्यान दें।
