यदि (f(x)=2x-2-1) और (g(x)=x-2+2) हैं, तो ((3f-2g)(x)) क्या होगा?

If (f(x)=2x-2-1) and (g(x)=x-2+2), what is ((3f-2g)(x))?

Explanation opens after your attempt
Correct Answer

A. \(4x^2-7\)

Step 1

Concept

(3f-2g=3\(2x^2-1\)-2\(x^2+2\)=4x-2-7). Sign mistakes in constant terms are common.

Step 2

Why this answer is correct

The correct answer is A. \(4x^2-7\). (3f-2g=3\(2x^2-1\)-2\(x^2+2\)=4x-2-7). Sign mistakes in constant terms are common.

Step 3

Exam Tip

(3f-2g=3\(2x^2-1\)-2\(x^2+2\)=4x-2-7)। स्थिर पदों में ऋण चिह्न की गलती आम होती है।
