यदि मूल (-5) और (4) हैं, तो मोनिक द्विघात समीकरण कौन-सा होगा?
If the roots are (-5) and (4), what will be the monic quadratic equation?
Explanation opens after your attempt
Correct Answer
A. \(x^2+x-20=0\)
Concept
The factors are ((x+5)) and ((x-4)). Multiplying them gives \(x^2+x-20=0\).
Why this answer is correct
The correct answer is A. \(x^2+x-20=0\). The factors are ((x+5)) and ((x-4)). Multiplying them gives \(x^2+x-20=0\).
Exam Tip
गुणनखंड ((x+5)) और ((x-4)) होंगे। इन्हें गुणा करने पर \(x^2+x-20=0\) मिलता है।
