Which option has roots (x=1) and (x=4)?
Explanation opens after your attempt
Correct Answer
A. \(x^2-5x+4=0\)
Concept
If the roots are (1) and (4), the factors are ((x-1)) and ((x-4)). Their product gives \(x^2-5x+4=0\).
Why this answer is correct
The correct answer is A. \(x^2-5x+4=0\). If the roots are (1) and (4), the factors are ((x-1)) and ((x-4)). Their product gives \(x^2-5x+4=0\).
Exam Tip
मूल (1) और (4) हों तो गुणनखंड ((x-1)) और ((x-4)) होंगे। इनका गुणन \(x^2-5x+4=0\) देता है।
