यदि (f(x)=x+6) और (g(x)=x-6) हैं, तो ((fg)(x)) का सरल रूप क्या है?
If (f(x)=x+6) and (g(x)=x-6), what is the simplified form of ((fg)(x))?
Explanation opens after your attempt
A. \(x^2-36\)
Concept
((fg)(x)=(x+6)(x-6)=x-2-36). This follows the \(a^2-b^2\) pattern.
Why this answer is correct
The correct answer is A. \(x^2-36\). ((fg)(x)=(x+6)(x-6)=x-2-36). This follows the \(a^2-b^2\) pattern.
Exam Tip
((fg)(x)=(x+6)(x-6)=x-2-36)। यह \(a^2-b^2\) का पैटर्न है।
