यदि मूल (-2) और (5) हैं, तो मोनिक द्विघात समीकरण कौन-सा होगा?
If the roots are (-2) and (5), what will be the monic quadratic equation?
Explanation opens after your attempt
Correct Answer
A. \(x^2-3x-10=0\)
Concept
The factors are ((x+2)) and ((x-5)), giving \(x^2-3x-10=0\). Make factors with signs opposite to the roots.
Why this answer is correct
The correct answer is A. \(x^2-3x-10=0\). The factors are ((x+2)) and ((x-5)), giving \(x^2-3x-10=0\). Make factors with signs opposite to the roots.
Exam Tip
गुणनखंड ((x+2)) और ((x-5)) होंगे, जिनसे \(x^2-3x-10=0\) मिलता है। मूल के विपरीत चिन्ह वाले गुणनखंड बनाएं।
