यदि (f(x)=2x-2+x) और (g(x)=x-2-x) हों, तो ((2f-g)(x)) क्या होगा?

If (f(x)=2x-2+x) and (g(x)=x-2-x), what is ((2f-g)(x))?

Explanation opens after your attempt
Correct Answer

A. \(3x^2+3x\)

Step 1

Concept

(2f(x)=4x-2+2x), then (4x-2+2x-\(x^2-x\)=3x-2+3x). Find (2f(x)) first.

Step 2

Why this answer is correct

The correct answer is A. \(3x^2+3x\). (2f(x)=4x-2+2x), then (4x-2+2x-\(x^2-x\)=3x-2+3x). Find (2f(x)) first.

Step 3

Exam Tip

(2f(x)=4x-2+2x), फिर (4x-2+2x-\(x^2-x\)=3x-2+3x)। पहले (2f(x)) निकालें।
