यदि (f(x)=2x-2) और (g(x)=3x-2) हों, तो ((5f-2g)(x)) क्या है?
If (f(x)=2x-2) and (g(x)=3x-2), what is ((5f-2g)(x))?
Explanation opens after your attempt
A. \(4x^2\)
Concept
((5f-2g)(x)=5\(2x^2\)-2\(3x^2\)=10x-2-6x-2=4x-2). Combine like terms at the end.
Why this answer is correct
The correct answer is A. \(4x^2\). ((5f-2g)(x)=5\(2x^2\)-2\(3x^2\)=10x-2-6x-2=4x-2). Combine like terms at the end.
Exam Tip
((5f-2g)(x)=5\(2x^2\)-2\(3x^2\)=10x-2-6x-2=4x-2)। like terms को अंत में combine करें।
