किस समीकरण के मूल (6) और (-2) हैं?
Which equation has roots (6) and (-2)?
Explanation opens after your attempt
A. \(x^2-4x-12=0\)
Concept
With roots (6) and (-2), we get ((x-6)(x+2)=0). Expanding it gives \(x^2-4x-12=0\).
Why this answer is correct
The correct answer is A. \(x^2-4x-12=0\). With roots (6) and (-2), we get ((x-6)(x+2)=0). Expanding it gives \(x^2-4x-12=0\).
Exam Tip
मूल (6) और (-2) होने पर ((x-6)(x+2)=0) होगा। इसे खोलने पर \(x^2-4x-12=0\) मिलता है।
